Recommend encrypting file before zipping.

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')

[Partha Mitra]

I tried both suggestions. But I am getting the message:

'7z' is not recognized as an internal or external command,

operable program or batch file.

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.
