How to reduce the decimal places if I want to save the mat file from the workspace?

Hi,
I handled my structure data, saved it in workspace and then output as mat file, but I don't want my file to be this large. How to reduce the decimal places if I want to save the mat file from the workspace? At first I used preferences to change variables, but it didn't reduce the storage of the mat file. How can I use any functions in MATLAB without coding?
Thank you so much.

Although with a touchscreen and the apps in the lint you can probably get quite some distance with a finger. Also no coding.

There are two options:
- Use a MAT format with compression: -v7.3 . See: doc save
- Convert doubles to singles or (U)INT32/16/8 arrays, if the loss of precision is no problem. CHAR arrays need 2 bytes per element also, so UINT8 might save some space.
There is no magic "make the output files smaller" flag.
