Large MAT-Files
Use thematfile
function to access MATLAB®variables directly from MAT-files on disk, without loading the full variables into memory. When you create a new file usingmatfile
, the function creates a Version 7.3 MAT-file that also lets you save variables larger than 2 GB.

Topics
Save and Load Workspace Variables
Save some or all variables in the current workspace and reload the variables later during the current MATLAB session, or during another session.
Save and Load Parts of Variables in MAT-Files
Save and load parts of variables directly in MAT-files without loading them into memory using thematfile
function.
There are several versions of MAT-files that each support an increasing set of features, starting with MAT-file Version 4.
Troubleshooting
文件大小增加Nonincrementally当增长Array
When writing a large number of large values to a MAT-file, the size of the file increases in a nonincremental way, which is expected.
