Hi There,

I'm trying to use codegen to generate generic C code for use on a DSP.

I'm using the following command, which used to work on an older version (2022b):

codegen -c -config:lib -d matlab_process_wrapper_lib matlab_process_wrapper.m -report -rowmajor -args types

Unfortunately, it is generating the following code, which is not compiling:

for (k = 0; k <= 252; k += 2) {

_mm_storeu_pd(&dv[k],

_mm_mul_pd(_mm_loadu_pd(&s[k]), _mm_loadu_pd(&s[k + 1])));

}

I'm wondering if I should use embedded coder but I can't find a similar page for the options as this, for coder: https://uk.mathworks.com/help/coder/ref/codegen.html

All suggestions would be most welcome.

Thanks very much,

John
