pure-Go MATLAB file I/O package ?

[Seb Binet]

hi there,

before I go ahead and implement it, has anyone released a pure-Go read/write package for MATLAB files ?

https://www.mathworks.com/help/pdf_doc/matlab/matfile_format.pdf

I've found:

 https://github.com/ready-steady/mat

but that package is actually using the C-API exposed by a MATLAB installation...

Maybe you already know this, but that PDF seems to cover the format
that was used by MATLAB Version 5 (R8). Versions since R2006b use an
HDF5-based format:

Unless you only need to work with the old format, you should look for
an HDF5 implementation in Go. I only found bindings for the C library.

Maxim,

thanks for taking the time to answer me.

yep. but the data I'll currently need to wrestle with is Level-5.

this one ?

github.com/sbinet/go-hdf5 ?

:)

HDF5 is a very VERY large (C) library and reimplementing it in pure-Go would be:

a) a huge task

b) very interesting

c) hair pulling

d) all of the above

the Level-5 (and Level-4) data file format(s) aren't that complicated.

I guess I'll bite the bullet and write the package.

Hi Sebastien, I'm writing a program that needs to do the exact same thing you were asking, have you by any chance developed that library? :P

I started it:

https://github.com/sbinet/matfio

but had to put it a bit on the back burner.

it's also a candidate for migration to a hypothetical github.com/gonum/io package...

PRs accepted :)
