Explain the difference between two commands. . 4) Among MATLAB Demos, illustrate an 3D example

Answer 1

[1] save(filename) saves all variables from the current workspace in a MATLAB® formatted binary file (MAT-file) called filename.

[3]
diary function use to keep an activity log of your session. ti will creates a verbatim copy of your MATLAB session in a disk file which not include graphics , audio file whereas save command used to keep any or all the variables in the current workspace to a MAT-file (.mat) because the workspace workspace clears When you quit MATLAB and if you want save and reuse just by loading the saved MAT-file.
