Description

Sometimes I have large .mat files, but I would like to only read a part of the file.

I noticed the following interface in mat7.3:

vars = mat73.loadmat('data.mat', only_include = ['var/subvar/subsubvar', 'tree1/'])

Would be nice to support some day in MAT.jl too

Research direction

Start by reviewing the linked mat7.3 interface and its only_include examples, then inspect how MAT.jl currently loads HDF5-backed trees. Done means supporting selective reads of paths such as var/subvar/subsubvar and tree1/ without reading the entire MAT file.
