I'm very new to Maple and I'm trying to get a 'diagonalisable' matrix set up.
It will help for me to attach what I currntly have for this to make sense:
What I currently have is a way of setting up a 5x5 matrix where it inserts a value at every instance where i=j, i=j+3 and i=j+6.
Currently I can only make this work for value from 1 to x and, for this to work, I basically need to make up a matrix that goes from -x to x
i.e currently I have x = 1 though 5 (5x5) and I need to set it up for x= -5 through 5 (11x11)
Every time I try and get the negative elements and 0 in there it tells me that I can't do it.
Is there any way to do this is Maple and am I going the wrong way about it?
Thanks very much for your time!
