Examples of Fortran MEX-Files

3-15

MEX-file. Consequently, when returning to MATLAB, the output matrix must

be transposed.

This example places a string array/character matrix into MATLAB as output

arguments rather than placing it directly into the workspace. Inside MATLAB,

call this function by typing

passstr;

You will get the matrix mystring of size 5-by-15. There are some manipulations

that need to be done here. The original string matrix is of the size 5-by-15.

Because of the way MATLAB reads and orients elements in matrices, the size

of the matrix must be defined as

M=15 and N=5 from the MEX-file. After the

matrix is put into MATLAB, the matrix must be transposed.

C from Fortran to MATLAB.

C Passes a string array/character matrix into MATLAB as

C output arguments rather than placing it directly into the

C workspace.
