Array indices must be positive integers or logical values.

It does not matter that you WANT V (0) to be something. MATLAB does not support zero based indexing. PERIOD. However, nothing stops you from starting the vector at V (1). And then when you index into the vector, just use V (ind + 1). Now when ind == 0, there is no problem. If you want to do a plot?1 Answer Sorted by: 0 If you are writing f (z) into matlab it means z index of array f.
