Description

MATIO is a C library for reading and writing MATLAB MAT files. The library is designed to be used by programs/libraries that handle MAT data files and do not have access to MATLAB shared libraries or do not want to depend on them.

module avail matio

warning

The current version is not compatible with the GPU A100 gpu_p5 and H100 gpu_p6 partitions!

Environment

The versions of MATIO are available in different environments. To list them, use the following command:

module show matio

To use this library in other environments, please contact the User Support team.
