Thread Subject:

Mat files in C programs

I am trying to read/write mat files in C programs. I think that would be
the most efficient way for me to load data in and out of matlab.

However, the matlab external interfaces documentation is horrible. It
gives only very simple examples. I could not locate a better
tutorial/book anywhere.

Any suggestions?

Also, is there a way to create .mat files in C programs on computers that
do not have matlab installed? i.e run my C program on the parallel
processors, create the mat files and read them in matlab?

Thanks a lot for your help in advance.

my e-mail address is below.

Hi Turgut,

The matcreat.c example in $MATLAB/extern/examples/eng_mat/ should give you an
idea of what it takes to create MAT-files from C. Then use the API reference
at
<http://www.mathworks.com/access/helpdesk/help/techdoc/apiref/apiref.shtml>
for more information about individual mat* and mx* functions.

You don't need to have MATLAB installed to use MAT-files. Take a look at the
following solution on our web site for more details:

Have fun!
