Consider creating model codeDescDemo or a model with similar specifications.

The model contains an n-D Lookup Table. The n-D Lookup Table block takes table data from a model workspace variable named tableData that has a value of [4 5 6]. The tableData is a Simulink.Parameter object with a non-Auto storage class. The breakpoint set data is specified as [1 5 10].

The model configuration parameter Default parameter behavior is set to Inlined.

1. Build the model and create a coder.codedescriptor.CodeDescriptor object for the model.

   codeDescObj = coder.getCodeDescriptor('codeDescDemo')

2. Retrieve properties of the Lookup Table block and breakpoint set in the generated code.

   params = getDataInterfaces(codeDescObj, 'Parameters')

   The params variable is an array of coder.descriptor.LookupTableDataInterface and coder.descriptor.BreakpointDataInterface objects.

     LookupTableDataInterface with properties:
                          Type: [1×1 coder.descriptor.types.Type]
                           SID: 'demoModel:22'
                 GraphicalName: 'tableData'
                   VariantInfo: [1×0 coder.descriptor.VariantInfo]
                Implementation: [1×1 coder.descriptor.DataImplementation]
                        Timing: [1×0 coder.descriptor.TimingInterface]
                          Unit: ''
                         Range: [1×1 coder.descriptor.Range]
            SupportTunableSize: 0
       BreakpointSpecification: 'Even spacing'
                        Output: [1×1 coder.descriptor.DataInterface]
                   Breakpoints: [1×1 coder.descriptor.BreakpointDataInterface Sequence]

3. The Breakpoints property of the coder.descriptor.LookupTableDataInterface object holds a vector of coder.descriptor.BreakpointDataInterface objects. Obtain the details of the breakpoint set attached to the Lookup Table block by accessing the first location in the array.

   params.Breakpoints(1)

     BreakpointDataInterface with properties:
                     Type: [1×1 coder.descriptor.types.Type]
                      SID: 'demoModel:22'
            GraphicalName: 'n-D Lookup↵Table'
              VariantInfo: [1×0 coder.descriptor.VariantInfo]
           Implementation: [1×0 coder.descriptor.DataImplementation]
                   Timing: [1×0 coder.descriptor.TimingInterface]
                     Unit: ''
                    Range: [1×1 coder.descriptor.Range]
           OperatingPoint: [1×1 coder.descriptor.DataInterface]
       SupportTunableSize: 0
          FixAxisMetadata: [1×1 coder.descriptor.FixAxisMetadata]

4. The new coder.descriptor.FixAxisMetadata object gives you more information about whether the breakpoint set data is evenly spaced or not.

   params.Breakpoints(1).FixAxisMetadata

   The information is returned as a new coder.descriptor.NonEvenSpacingMetadata object that has these properties:

     NonEvenSpacingMetadata with properties:
       AllPoints: [1×3 Real Sequence]
