Try passing your matrix into your function, like
newM = yourFunction(M)
where you define your operations in the function. For example to cube it (element by element) and add 4:
function newM = yourFunction(M)
newM = M .^ 3 + 4;

Thank you ! I guessed it should work that way but I coudlnt understand how to define functions properly.
I also found that using Arrayfun does the job pretty well, Thanks
