Read Matlab's .mat file in C -


i using matlab generate large matrix, , want use in c.

how can read matlab's .mat file in c?

if possible, please answer how?

supposedly matlab provides own api access such files c: read , write mat files. haven't used myself, don't know how straightforward is.

if want access binary data, search engine came pdf file, matfile_format.pdf, describes entire format. not easy solution.

you can read such files in python however, see this topic. reading file way , writing again in format that's easy use in c seems solution.
