Hi, I want to save a large data 3^14*1000 double precision to mat file, however, matlab reports error as:
Warning: Variable 'a' cannot be saved to a MAT-file whose version is older than 7.3. To save this variable, use the -v7.3 switch. Skipping...
And it cannot be saved.
I can change the precision to single but it is still very large, >1 GB. Is there a way matlab can save large data to a mat file? Thanks.
