Hello

My matlab version is R2019b. I have visual studio 2017 with intel oneAPI 2021 installed. However, when I type the following, I get error:

Any guidance, especially from MatLab staff is highly appreciated as otherwise I have to code the program on my own in MatLab.

mex -setup FORTRAN

Thanks for your reply.

I saw that link before, thats why I downloaded VS2017 to be compatible to Matlab R2019b. So, the only issue is making the compiler support R2019b. However, I do not know how should I edit the xml file?

it is the list of compiler components in my R2019b, which shows intel fortran 17,18,19 are supported in R2019b. Could you please tell me how should I edit this? what is the guidance to edit xml file?

Thanks. I editted the xml file according to your guidance and named it intel_one_classical_fortran_vs2017.xml . then Could you please tell me why am I getting this error?

            <and>
                <or>
                    <envVarExists name="ONEAPI_ROOT" />
                </or>
                <fileExists name="$$/bin/intel64/ifort.exe" />
                <dirExists name="$$/../.." />
        </and>

Did not find installed compiler 'Intel oneAPI Fortran compiler with Microsoft Visual Studio 2017'.
Error using mex
MEX cannot use compiler 'Intel oneAPI Fortran compiler with Microsoft Visual Studio 2017' because that compiler is not found.

"Looking for file 'C:\Program Files (x86)\Intel\oneAPI\compiler\2021.4.0\windows\bin\intel64\bin\intel64\ifort.exe' ...No."

You have to check where is the intel fortran compiler is installed on your system and adapt accordingly.

I don't have access to your system or never work with intel fortran, you have to figure out on your own.
