The AcceptExprInput value flags the code generator that the implementation function described by this entry accepts expression inputs. The default value is true if ImplType equals FCN_IMPL_FUNCT and false if ImplType equals FCN_IMPL_MACRO.

If the value is true, expression inputs are integrated into the generated code in a form similar to this form:

 rtY.Out1 = myAdd(rtU.In1, rtU.In2 * rtU.In3);

If the value is false, a temporary variable is generated for the expression input:

real_T temp;

temp = rtU.In2 * rtU.In3;
rtY.Out1 = myAdd(rtU.In1, temp);

Example: 'AcceptExprInput',true

The AdditionalHeaderFiles value specifies additional header files for a code replacement table entry. The character vectors or string array can include tokens.

Example: 'AdditionalIncludePaths',{}

The AdditionalLinkObjs value specifies additional link objects for a code replacement table entry. The character vectors or string array can include tokens.

The AllowShapeAgnosticMatch value enables code replacement match based on total number of elements rather than specific matrix shape for matrices that are contiguously allocated in memory. For more information, see Allow Shape Agnostic Match.

Example: 'AllowShapeAgnosticMatch', false

The ArrayLayout value specifies the order of array elements in memory supported by the replacement implementation. By default, the replacement implementation supports column-major data layout. For ROW-MAJOR, the replacement implementation supports row-major data layout. For COLUMN_AND_ROW, the replacement implementation supports column-major and row-major data layouts.

Example: 'ArrayLayout','ROW_MAJOR'

The EntryInfoAlgorithm value specifies the algorithm for the specified math function that must be matched for operator replacement to occur. Code replacement libraries support replacement based on the algorithm for math operations RTW_OP_ADD and RTW_OP_MINUS. Valid arguments for the supported operations are listed in the table. The arguments have the same meaning for both operations.

Example: 'EntryInfoAlgorithm','RTW_CAST_AFTER_OP'

The GenCallback specifies a callback that follows code generation. If you specify 'RTW.copyFileToBuildDir', and if this operation entry is matched and used, the code generator calls function RTW.copyFileToBuildDir after code generation. This callback function copies additional header, source, or object files that you have specified for this entry to the build folder.

Example: 'GenCallback','RTW.copyFileToBuildDir'

The ImplementationHeaderFile value specifies the name of the header file that declares the implementation function. The character vector or string scalar can include tokens. For example, in the token $mytoken$, mytoken is a variable defined as a character vector or string scalar in the MATLAB workspace or as a MATLAB function in the search path that returns a character vector.

Example: 'ImplementationHeaderFile','s32_mul.h'

The ImplementationHeaderPath value specifies the full path to the implementation header file. The character vector or string scalar can include tokens. For example, in the token $mytoken$, mytoken is a variable defined as a character vector or string scalar in the MATLAB workspace or as a MATLAB function in the search path that returns a character vector.

Example: 'ImplementationHeaderPath', fullfile('$MATLAB_ROOT', 'crl')

The ImplementationName value specifies the name of the implementation function, which can match or differ from the Key name.

Example: 'ImplementationName','s32_mul_s32_s32_sat'

The ImplementationSourceFile value specifies the name of the implementation source file. The character vector or string scalar can include tokens. For example, in the token $mytoken$, mytoken is a variable defined as a character vector or string scalar in the MATLAB workspace or as a MATLAB function in the search path that returns a character vector.

Example: 'ImplementationSourceFile','s32_mul.c'

The ImplementationSourcePath value specifies the full path to the implementation source file. The character vector or string scalar can include tokens. For example, in the token $mytoken$, mytoken is a variable defined as a character vector or string scalar in the MATLAB workspace or as a MATLAB function in the search path that returns a character vector.

Example: 'ImplementationSourcePath', fullfile('$MATLAB_ROOT', 'crl')

The ImplType value specifies the type of table entry. Use FCN_IMPL_FUNCT for function or FCN_IMPL_MACRO for macro.

Example: 'ImplType','FCN_IMPL_FUNCT'

The Key value specifies the key for the operator to replace. The key must match an operator key listed in Code You Can Replace from MATLAB Code or Code You Can Replace From Simulink Models.

Example: 'Key','RTW_OP_ADD'

The MustHaveZeroNetBias value specifies whether a replacement match requires that the net bias for conceptual arguments of Add/Minus entries is zero. For the Add/Minus of fixed-point operator inputs and output this parameter must be set to true. Instantiate the entry by using hEntry = RTW.TflCOperationEntryGenerator rather than hEntry = RTW.TflCOperationEntry.

For Mul/Div/MulDiv/Shift/Cast entries:

Example: 'MustHaveZeroNetBias',true

The NetSlopeAdjustmentFactor value specifies the fixed exponent (E) part of the net slope (F2^E, for example, -3.0) for fixed-point conceptual arguments required for a replacement match to occur for Mul/Div/MulDiv/Shift/Cast entries. Instantiate an entry by using hEntry = RTW.TflCOperationEntryGenerator_NetSlope rather than hEntry = RTW.TflCOperationEntry.

For Add/Minus entries:

Example: 'NetFixedExponent', -3.0

The NetSlopeAdjustmentFactor value specifies the slope adjustment part of the net slope (F2^E, for example, 1.0) for fixed-point conceptual arguments required for a replacement match to occur for Mul/Div/MulDiv/Shift/Cast entries. Instantiate an entry by using hEntry = RTW.TflCOperationEntryGenerator_NetSlope rather than hEntry = RTW.TflCOperationEntry.

For Add/Minus entries:

Example: 'NetSlopeAdjustmentFactor',1.5

The Priority value specifies the search priority of the operation entry, relative to other entries of the same operation name and conceptual argument list within this table. Highest priority is 0, and lowest priority is 100. If the table provides two implementations for an operation, the implementation with the higher priority shadows the one with the lower priority.

Example: 'Priority',100

The RoundingModes value specifies one or more rounding modes supported by the implementation function.

Example: 'RoundingModes',{'RTW_ROUND_UNSPECIFIED'}

The SaturationMode value specifies the saturation mode supported by the implementation function.

Example: 'SaturationMode','RTW_SATURATE_UNSPECIFIED'

The SideEffects value flags the code generator not to optimize away the implementation function described by this entry. This parameter applies to implementation functions that return void but are not to be optimized away, such as a memcpy implementation or an implementation function that accesses global memory values. For those implementation functions only, you must include this parameter and specify the value true.

Example: 'SideEffects',false

The SlopesMustBeTheSame value specifies whether a replacement match requires that the slope is the same for conceptual arguments of Mul/Div/MulDiv/Shift/Cast entries. Instantiate the entry by using hEntry = RTW.TflCOperationEntryGenerator rather than hEntry = RTW.TflCOperationEntry.

For Add/Minus entries:

Example: 'SlopesMustBeTheSame',true

The StoreFcnReturnInLocalVar value flags the code generator that the return value of the implementation function described by this entry must be stored in a local variable regardless of other expression folding settings. If the value is false, other expression folding settings determine whether the return value is folded. Storing function returns in a local variable can increase the clarity of generated code. This example shows code generated with expression folding:

void sw_step(void)
{
    if (ssub(sadd(sw_U.In1, sw_U.In2), sw_U.In3) <= 
        smul(ssub(sw_U.In4, sw_U.In5),sw_U.In6)) {  
      sw_Y.Out1 = sw_U.In7;  
    } else {
       sw_Y.Out1 = sw_U.In8;  
    }
}

With StoreFcnReturnInLocalVar set to true, the generated code is potentially easier to understand and debug:

void sw_step(void)
{  
    real32_T rtb_Switch;  
    real32_T hoistedExpr;
    ......  
    rtb_Switch = sadd(sw_U.In1, sw_U.In2);
    rtb_Switch = ssub(rtb_Switch, sw_U.In3);
    hoistedExpr = ssub(sw_U.In4, sw_U.In5); 
    hoistedExpr = smul(hoistedExpr, sw_U.In6);  
    if (rtb_Switch <= hoistedExpr) {
       sw_Y.Out1 = sw_U.In7;  
    } else { 
       sw_Y.Out1 = sw_U.In8;  
    }
}

Example: 'StoreFcnReturnInLocalVar',false
