How do you do arrays

[Kartic]

Tom,

Before you use iMatrix[index], you have to tell python to use iMatrix
as an array. You will do that using iMatrix = [] *outside* the loop.

iMatrix = []
while index < majorlop1: # rest of the loop statements

Since you are new, please take a look at the Python tutorial to get you
started.
