- Description
- A MAT-file holds the variables saved from a MATLAB session: numeric arrays such as matrices and images, text, cell arrays and structs. Files saved with -v7.3 are HDF5 files behind a MATLAB header. Unity and Unreal material files use the .mat extension too, but they are a different format.
- A JPEG XL file is an image saved in a compressed graphic format currently under development by the Joint Photographic Experts Group (JPEG). It supports wide color gamut and HDR (High Dynamic Range), alpha channels and animation frames while providing visually lossless compression. Images can be converted back and forth between JPEG XL and JPEG without loss of quality. Converting a regular JPEG to JPEG XL reduces the file size by 22%. JPEG XL files can be used to store any type of image content.
