Octave Mat File Format

Save the data in octave s text data format.

Octave mat file format. If you do not specify filename the load function searches for a file named matlab mat. If filename has no extension that is no period followed by text and the value of format is not specified then matlab appends mat if filename does not include a full path matlab saves to the current folder. Loading the data set directly in octave matlab. This repository contains a file mnist mat created from this data set which can easily be loaded with octave or matlab.

It is not expected to work for matlab s new hdf5 based mat file format or any other arbitrary hdf5 files. I bet this is also a duplicate of another report but i haven t checked. Better if i can save a mat file in octave. Force octave to assume the file is in matlab s version 6 or 7 binary format.

The files are saved in your current directory as seen on the top of the window. Octave s load function is only expected to be able to read hdf5 files that are created by octave s save function in hdf5 format. Name of file specified as a character vector or string scalar. Save the data in the binary format written by matlab version 4.

Matlab recently introduced the v7 3 save option which is an hdf5 format which is particularly useful for 64 bit platforms where the standard matlab format can not correctly save variables. I ve marked this as a feature request. Diary filename saves all the text input in the command window to a text file. There are some differences in the mat v5 file format accepted by octave.

If filename has no extension that is no text after a period load looks for a file named filename mat if filename has an extension other than mat the load function treats. Save saves data to files mat by default not true in octave 4 files have no extension uisave includes user interface. Hgsave saves figures to files fig by default. Octave accepts hdf5 files but is not yet compatible with the.

This works equally on files that are compressed with gzip outside of octave and gzip can equally be used to convert the files for backward compatibility. Force octave to assume the file is in the binary format written by matlab version 4. Anyway if what you want is to save data in the matlab binary format have a look at the mat binary option for the save command. On platforms other than windows the file extension does not necessarily relate to the data format.

Use the gzip algorithm to compress the file. Name of file specified as a character vector or string scalar. Either you can use this file directly or you can create it with the mnist py python script contained in this repository.
