IDL routine to read MATLAB MAT-files [message #75524]

Hi All

I've written an IDL routine to read MATLAB MAT-files. I thought that
this routine may be useful to others on this list, so I've made the
code available at GitHub:

https://github.com/gordonfarquharson/idl-load-mat

The routine is by no means complete: for instance, there are several
variable types that it does not support. However, the code is written
in such a way that it should be easy to extend. Note that the routine
does not read the newer HDF5 format MAT-files (see the README file for
more information).

If you find problems with the code, please use the tools at GitHub to
let me know about it. I don't have a huge amount of time to work on
this routine, but I'll see what I can do. Also, if you do extend the
program to support a new type, it would be great if you could let me
know so that we can incorporate your improvements.

You can checkout a copy of the code using git, or f you are not git-
savvy, GitHub allows you to download the code as a compressed tar file
or as a ZIP file.

My development branch is now available on GitHub. It contains a
version of the code that supports endian swapping. With this code, one
should be able to read big-endian MAT-files (written using a big-
endian machine) on a little-endian machine (tested), and visa versa (I
am not able to test reading little-endian MAT-files on a big endian
machine).

Thanks Gordon,
I work with several Matlab folks, and this will probably turn out to be very
useful for me.

cheers,
bob

fyi, I have updated the load_mat routine to handle compressed mat files. the updated code is now included with my public IDL library here:

So if I have .mat file I can convert it to IDL and get it work? Is that what you mean? I have .mat file and I want to use IDL and I'm not good in IDL just learning and I'm using Matlab

Thanks
