When working with these large.
Load and save mat file in matlab.
Name of file specified as a character vector or string scalar.
Save and load parts of variables in mat files.
The primary advantage of using the matfile function over the load or save functions is that you can process parts of very large data sets that are otherwise too large to fit in memory.
However you can save any or all the variables in the current workspace to a mat file mat you can then reuse the workspace variables later during the current matlab session or during another session by loading the saved mat file.
First create the mat file object m.
Disp save variables to mat file disp save example mat matvar1 matvar2 matvar3 save example mat matvar1 matvar2 matvar3.
Filename can include a file extension and a full or partial path.
If you do not specify filename the save function saves to a file named matlab mat.
If you do not specify filename the load function searches for a file named matlab mat.
The workspace is not maintained across sessions of matlab when you quit matlab the workspace clears.
Access specific parts of a variable in a mat file using the mat file object.
For example you can save data to a subset of a variable in a mat file or read a subset of a variable into the matlab workspace.
Save variables matvar1 matvar2 and matvar3 in a matlab formatted binary file mat file called example mat.
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.
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.
Name of file specified as a character vector or string scalar.
