About libgfortran.3.dylib (no such file)

When I run a toolbox in Matlab, MEX file error.

such as follow:

'/Applications/Polyspace/R2021a.app/GPOPS2/nlp/snopt/snoptcmex.mexmaci64' 无效:

dlopen(/Applications/Polyspace/R2021a.app/GPOPS2/nlp/snopt/snoptcmex.mexmaci64, 0x0006): Library not loaded:

/sw/lib/gcc4.4/lib/libgfortran.3.dylib

Referenced from: /Applications/Polyspace/R2021a.app/GPOPS2/nlp/snopt/snoptcmex.mexmaci64

Reason: tried: '/sw/lib/gcc4.4/lib/libgfortran.3.dylib' (no such file), '/usr/local/lib/libgfortran.3.dylib' (no such

file), '/usr/lib/libgfortran.3.dylib' (no such file)

I think it is the reason about Apple M1.

Wish to be helped to solve the problem!!
