Load Mat File In Octave

Save the data in octave s text data format.

Load mat file in octave. Force octave to assume the file is in octave s text format. Octave s default so called mat file format is not a binary mat file at all it is in fact a text file format that octave developed for itself. Saving with save ascii and simply load in matlab however did work. Saving with save v7 in octave and simply load in matlab did not work.

A double array is returned. Bottom line is that you can say. This is explained in the octave documentation. Saving with save mat7 binary or save v7 and loading with load mat also works but a struct is created in matlab.

Force octave to assume the file is in the binary format written by matlab version 4. Name of file specified as a character vector or string scalar. By default the current directory is octave work. Default this proprietary text format is not and never has been compatible with any of the publicly documented mat binary file formats.

Not sure which version of mat file you might have or whether octave keeps up with the latest matlab formats. I ve done this before and it was not difficult but was time consuming. This corresponds to the load documentation in matlab. The file must be in a recognized directory usually your current directory but at least one for which the path has been set.

Force octave to assume the file is in matlab s version 6 or 7 binary format. The save and load commands allow data to be written to and read from disk files in various formats. In case you wind up having to write code to read the mat file ever. Save dlmwrite csvwrite fwrite.

Likewise there are many ways to load files into the workspace to load a saved mat file type. However i think some sort of workaround is needed for being able to load existing mat files that trigger such issue so octave users can access the rest of the data ideally informing the user about what variables empty function handles are missing and why. Here s a link that might be a good start. As an example the following code creates a 3 by 3 matrix and saves it to the file myfile mat.

14 1 3 simple file i o. Filename can include a file extension and a full or partial path. Load mymatfile mat right at the octave prompt. If you do not specify filename the load function searches for a file named matlab mat.

This is explained in the octave documentation. Default this proprietary text format is not and never has been compatible with any of the publicly documented mat binary file formats. The default format of files written by the save command can be controlled using the functions save default options and save precision. This is the first time i ve had octave fail to be matlab binary compatible.

Octave failed to read it both with plain load quad3 mat and also with load mat binary quad3 mat inspection of the file showed matlab 5 0 at the head.
