[Octave-bug-tracker] [bug #51741] zlib error when loading .mat file on Windows 10 64bit

[Mike Miller]

Follow-up Comment #8, bug #51741 (project octave):

This is a wild guess, but please make sure that you do not have another copy
of the file somewhere on Octave's load path. Most Octave functions, including
fileread and load, will find a file by name on the load path, so you may not
be trying to use the copy of the file that you think you are. Or use the
absolute path to be sure.

As long as that's not the simple solution, it looks like you're on the right
path of debugging this. You may want to look at the size of the buffer that
fileread returns, make sure it's the right number of bytes. Or try reading the
file with fread in increasing blocks and see if you can figure out where it
goes wrong, if there is some size threshold or a particular byte that is
interpreted badly by Octave for some reason.
