It means you tried to access an array at an index that is too large to fit in the array.
For example,
m = magic(4);
would be a 4 x 4 array, so (for example) m(2,3) and m(:,4) are valid indexes for m. But if I tried to index m(1,5) then I would be trying to access a column that does not exist in the array.
