I keep getting index exceeds matrix dimensions but I don't understand why. I'm trying to sum the elements in an array.

Below is a simple code. I'm creating an array m which contains all odd numbers between 1 and 52015. I'm trying to sum all the elements in the array. I keep getting "Index exceeds matrix dimensions.Error in oddsum (line 33), odd = sum(n). I wasn't sure if transposing m would help solve the problem, but I don't understand how the index exceeds the dimensions of my matrix.

m = 1:2:52015;

n = m';

odd = sum(n); -- this is where my error is

Somewhere earlier in your code you have a variable named ‘sum’ that is ‘overshadowing’ the sum function. Rename the variable to something other than ‘sum’ (or the name of any other MATLAB function) and the problem will disappear.
