Chris, thanks. I have experimented a bit and have some results and
some questions which remain. Here goes.
I have written a little modification to symarray called csymarray. I

It sounds like you want to actually create the variables a_00 =
Symbol('a_00'), a_01 = ... in the active namespace.
In a previous e-mail you wrote that you wanted something like the following
for i in range(1,3):
for j in range(1,3):
aij = Symbol('a_%d%d' % (i,j))
Unfortunately
So, it seems that ZS is defined and has length 3. So it is three
'vectors'. But the individual components are not defined? Who ordered
that? I want to create the 3x3 matrix and then create a new symmetric
matrix from ZS ( the 'S' in the name ZS is for using the Symbol()
rather than
Hi Matt,
Thanks for the reply!

Matt,
Thanks for the suggestions. Way 2 is more what I want to do(but not
quite) right now, but having the capability to do it via way 1 will be
welcomed!

Miham,
Thanks for the suggestion. It is rather elegant. However, I really
want to be able to assign a more convenient label to the created
symbols. That is, I want to assign
a11 - a_11, a12 - a_12, etc as the new symbols are defined. In a
loop would be nice, but I can not seem to get the
Hi Ondrej,
Your suggestion is very useful. I am now defining a matrix array with
element notation a_ij and label aij whereas your suggestion seems to
result in a_i_j and no more convenient to type label such as my
desired aij. How to do this?
