Octave save mat file. Ideally a script that iterated over all files with the mat extension in my directory would be ideal but this got the job done. Hgsave saves figures to files fig by default. Save options file v1 v2. As an example the following code creates a 3 by 3 matrix and saves it to the file myfile mat.

The files are saved in your current directory as seen on the top of the window. Someone brought me a diskette today with data computed by matlab 5 1 i was told in a matlab mat file. Octave fails to read. Name of file specified as a character vector or string scalar.

You may have a mat file that you want to read into scipy. Start octave octave at the command line for me. 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. There are some differences in the mat v5 file format accepted by octave.

The default format of files written by the save command can be controlled using the functions save default options and save precision. Octave failed to read it both with plain load. Diary filename saves all the text input in the command window to a text file. 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.

The workspace is not maintained across sessions of matlab when you quit matlab the workspace clears. It saves the data as two space separated columns of data. 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. Save and load workspace variables.

Or you want to pass some variables from scipy numpy into matlab. Save v1 v2. Better if i can save a mat file in octave. If you do not specify filename the save function saves to a file named matlab mat.

Save options file struct struct f1 f2. S save v1 v2 save the named variables v1 v2 in the file file. Octave has matlab compatible save and load functions. The special filename may be used to return the content of the variables as a string if no variable names are listed octave saves all the variables in the current scope.

To save us using a matlab license let s start in octave. On platforms other than windows the file extension does not necessarily relate to the data format. Save saves data to files mat by default not true in octave 4 files have no extension uisave includes user interface.
