Save in a .mat file(); you will get much better compression: https://www.mathworks.com/help/matlab/import_export/mat-file-versions.html. In the bin file, each double number will take a full 8 bytes.

I have a variable dimension 
double in workspace.This contains 4 individual physiological data in 4 rows. I want to save this variable with lowest possible size in the current folder. If I am not wrong the file format should be binary. How do I save this variable in current folder as a .bin file sothat later I can load it and work with it?
