- 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.
- Compressed bitmap image that uses wavelet compression instead of the DCT compression used by standard .JPEG images; supports 16-bit color, alpha transparency, and lossless compression.
