Internal Error: Evaluation of validate function on class hdldefaults.LookupTableND failed with the error message: MATLAB:UndefinedFunction: Undefined function 'storedInteger' for input arguments of type 'double'.

How can I solve this error ? Is anything I do not intall?

My matlab version is R2021a, and my model is in attachment.

Could you provide more information regarding the Simulink model by sharing the file or snapshots of the model ?

Hello Kris,

The documentation for n-D Lookup Table shows that HDL Code Generation for is supported for 'Flat' and 'Linear point-slope' interpolation methods. In the Restrictions section, it also indicates that when the Interpolation method is set to 'Flat', the block supports 'half' data type for inputs, breakpoints and outputs. In the attached model, the restriction condition isn't met as the Interpolation method has been set to 'Flat' but the input data type isn't 'half'. You could vary the datatype of the inputs or change the interpolation appropriately adhering to the constraints mentioned in the documentation page.

For more information you could refer to the documentation page for n-D Lookup Table.

Hope this helps!
