    Octave-4.4.1.app/Contents/Resources/usr/Cellar/openblas_0.3.3_0/0.3.3/include/f77blas.h

So, my question is, how can I make it successfully find and use that header file when calling install_sedumi?

Can you show the result of the following command in the Octave app:

   mkoctfile -p ALL_CFLAGS

That should reveal the default include directories of "mex" aka "mkoctfile --mex".  Maybe you can add to "install_sedumi" [1] something like

   flags{end+1} = '-I/Octave-4.4.1.app/Contents/Resources/usr/Cellar/openblas_0.3.3_0/0.3.3/include';

that "mkoctfile" and "mex" can find your header.

Best,

Kai
