Why is the 'sum' function also outputting elements of my matrix?

I have a column vector that I am trying to take the sum of, but I want it to display only the sum. Every time I use the sum function it also spits out every element in the matrix, along with the sum, which I do not want it to do. This seemed like an easy fix, but I couldn't find anything online.

Did you write your OWN function called sum? Type this on the command line:
which sum -all
If you have written a function called sum, it will then show up. Delete it, as sum is a tremendously important tool in MATLAB. At the very least rename it, or move it off your search path.
The fact is, sum does NOT do as you describe, so the only way what you describe can happen is if you did exactly what I suggest.

Wait, I made a dumb mistake. Didn't notice I forgot to suppress output of that matrix in another line of the code. I think after adding the sum(A) part I changed part of my code elsewhere as well leading me to believe the sum-function of Mat lab was glitched. Thanks for a timely response though.
