Index Problem in for loop

I am having a rather basic problem that I still cant figure it out.

I have two arrays: both have a 64x1 dimension but one is the result of a foor loop using angle as the index (alpha = 25:89). On the other hand the other array has been defined as follows (i = 1:64)

How can I multiply each variable of these arrays without getting the following error: Index in position 1 exceeds array bounds (must not exceed 64).

"...one is the result of a foor loop using angle as the index (alpha = 25:89)"

That is the start of your problems: confusing data with code. This approach is fragile and inefficient. Any negative, zero, or fractional values will throw an error. Any "missing" angles (up to the maximum) will still have stored values in the data array, but serve no purpose.

A much more robust approach would be to store the angles in one vector and the results in another. Then all of your data vectors will have exactly the same size.

Very good I got the conccept right away, Thank you!

I did it and it worked, Thanks!
