The previous article was about scigolib/hdf5 , a pure Go HDF5 library born out of the need to read MATLAB data in Go. This is the other half of that story: scigolib/matlab , the library that actually reads the .mat files.

It reads and writes both MATLAB formats in pure Go, with no cgo:

v5 (MATLAB v5 to v7.2): the classic binary format, including the zlib-compressed elements MATLAB writes by default;

v7.3 : HDF5 underneath, through scigolib/hdf5.

What works today: every numeric class, complex numbers, multi-dimensional arrays, reading char arrays, both byte orders, 32-bit targets in CI, and a fuzz-tested v5 parser.…
