- 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 PJPEG file is a bitmap image created in the Progressive JPEG format (PJPEG). It contains encoded bitmap data so that the downloaded image appears progressively from a blurry picture to the final sharp image. PJPEG files may also fill alternating horizontal lines until the full picture is revealed.
