- 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 PPM file is a 24-bit color image formatted using a text format. It stores each pixel with a number from 0 to 65536, which specifies the color of the pixel. PPM files also store the image height and width, whitespace data, and the maximum color value.
