MATLAB: How to use integer inputs to a Fortran MEX-file in MATLAB

Question

I would like to write a Fortran MEX-file that accepts integer values for input. I cannot find an example in the documentation that shows how to do this.

Answer 1

This change has been incorporated into the documentation in Release 2010a (R2010a). For previous releases, read below for any additional information:

Documentation on using integer inputs to a Fortran MEX-file is missing from MATLAB.

Download the attached Fortran MEX-file for example code. To run the example:

1. Set up your Fortran compiler:

mex -setup

2. Compile the downloaded Fortran MEX-file using the compiler from step 1, above:

mex xtyint.f

3. Execute the example:

x = int32(7)
y = int32(1:100)
z = xtyint(x, y)
