codegen is by default replacing multiplication with cblas_sgemm though the header file have fun definition with different name.

What is the correct approach. I want to replace maths operators with BLAS?

classdef ifxcallback < coder.BLASCallback
    methods (Static)
        function updateBuildInfo(buildInfo, ~)
            buildInfo.addSourceFiles(fullfile(pwd,'BLAS','src.c'))
            buildInfo.addIncludePaths(fullfile(pwd,'BLAS'));
        end
        function headerName = getHeaderFilename()
            headerName = 'inc.h';
        end
        function intTypeName = getBLASIntTypeName()
            intTypeName = 'int';
        end
    end
end
function p = useEnumNameRatherThanTypedef()
p = true;
end

@Ryan Livingston Thank you very much for the proposal to raise an internal request. I, like many others are certain to find the curated list extraordinarily helpful. It helps prioritizing development activities.

Thanks a lot, again.

@Ryan Livingston Assuming that a sequence of mathematical operation have been described using simulink operators (e.g. multiply, add, transpose), it should be possible to generate either a BLAS call or perhaps a call to a function defined in the code replacement library. In a specific case such as matrix multiply, it should be possible for code generator to either generate cblas_sgemm() or crl_matrix_multiply(). Given availability of two alternative definitions, is it possible to prioritize one code replacement style over other?

For e.g. can i get code for operator matrix multiplication mapped to BLAS function while getting the code for the matrix transpose operator mapped to function defined in code replacement library?
