MATLAB: Does “sortrows” not work with a semicolon

Question

Could someone clarify this issue I am having?

I tried to sort the rows of a matrix by the first column (in descending order)…

sortrows(P, -1) % works fine

But, for some reason:

sortrows(P, -1); % does not work!

Is this a known issue?

Answer 1

Remember, sortrows(P,-1); would sort the rows and then would throw away the results because you did not write them to a variable.
