Does "sortrows" not work with a semicolon?

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?

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

Well spotted, Walter & Sean.

It does work, but it throws away the result, of course.

I guess I was "doing in Matlab and thinking in Excel"

Works fine for me. I did this:

a = magic(5);
b = sortrows(a,-1);

When you say, does not work, do you mean it gives you an error, or it does not sort properly?
