Add algorithm properties for code replacement table entry
addAlgorithmProperty(hEntry, name-value)
hEntryHandle to a code replacement table entry
previously returned by instantiating a code
replacement entry class, such as
hEntry =
RTW.TflCFunctionEntryhEntry =
RTW.TflCOperationEntry
name-valueAlgorithm property, specified as a comma-separated pair consisting of the name of an algorithm property and one or more algorithm values. Specify multiple values as a cell array of character vectors.

The addAlgorithmProperty function
adds algorithm property settings to the conceptual
representation of a code replacement table entry.
For example, use this function to adjust the
algorithms applied by lookup table
functions.
In the following example, the
addAlgorithmProperty function
configures the code generator to apply the
following methods when replacing code for the
lookup1D function:
Clip extrapolation
Linear interpolation
Binary or linear index search
