Build Fortran MEX File
This example shows how to build the example MEX file,
timestwo
. Use this example to verify the build
configuration for your system.
To build a code example, first copy the file to a writable
folder, such as c:\work
, on your path:
copyfile(fullfile(matlabroot,'extern','examples','refbook','timestwo.F'),'.','f')
Use the mex
command to build the MEX file.
mex timestwo.F
This command creates the file
timestwo.
,
where ext
ext
is the value returned by the
mexext
function.
The timestwo
function takes a scalar input and
doubles it. Call timestwo
as if it were a
MATLAB® function.
timestwo(4)
ans = 8
