Sorry I modified my earlier comment:
7z a archive.7z -psecret *.mat
I was getting error.
Error: Unexpected MATLAB expression. (Used Matlab R2017b)
What do I have to do to encrypt *.mat file

! 7z a archive.7z -psecret *.mat
or
system('7z a archive.7z -psecret *.mat')

I also tried with full path where 7z is installed as below:
system('C:\Program Files\7-Zip\7z.exe a archive5.7z -psecret *.mat')
But it is not correct as I am getting similar error:
'C:\Program' is not recognized as an internal or external command,
operable program or batch file.

It worked, with following way:
system('"C:\Program Files\7-Zip\7z.exe" a arc.7z -psecret *.mat')

Using an exact path like you did is often a good idea for reliability... on any one system... but unfortunately not always portable.
