Hello, I noticed that Matlab was returning the error "Index exceeds matrix dimensions" when running this default script:

%%Sum of Vector Elements
% Create a vector and compute the sum of its elements.
% Copyright 2015 The MathWorks, Inc.
A = 1:10;
S = sum(A);

How can I fix that? Thanks in advance!

In your Command Window, type:

which sum -all

If the first on the list of results is:

sum is a variable.

you have your answer.

The ‘fix’ is to rename your ‘sum’ variable to something else that makes sends in the context of your code, for example ‘sum_v’.
