matlab stored data is larger than 2GB

Notebook general, when the mat is greater than 2GB of data, usually not directly stored, given as follows:

Save operation failed. this variable cannot be saved to a MAT-file whose version is older than 7.3,because it is too large.

This situation, if you want to continue saving, can be converted into 7.3.

Example: Save ( 'myFile.mat' , '-v7.3' );
