The ultimate goal should be to get code into Sage since there is
nearly always common code to factor out and getting more users for
some

Thanks - I didn't know (being a COMPLETE newbie) about the "range"
command. Where in the documentation would I find this? - I've had a
bit of a search and couldn't find it.
Thanks again,

I think the order of the i and j is transposed (assuming row i and
column j):
sage: M = matrix(5,5,[[1/(i+j%2) for j in range(1,6)] for i in range
(1,6)])
sage: M
[1/2 1 1/2 1 1/2]
[1/3 1/2 1/3 1/2 1/3]
[1/4 1/3 1/4 1/3 1/4]
[1/5 1/4 1/5 1/4 1/5]
[1/6 1/5 1/6 1/5 1/6]
s
M = matrix(5,5,[[1/(i
One way to do it (for a 10x10):
sage: n = 10
sage: M = Matrix(n,n,[[1/(i+j) for i in range(1,11)] for j in range(1,11)])
sage: M
[ 1/2 1/3 1/4 1/5 1/6 1/7 1/8 1/9 1/10 1/11]
[ 1/3 1/4 1/5 1/6 1/7 1/8 1/9 1/10 1/11 1/12]
[ 1/4 1/5 1/6 1/7 1/8 1/9 1/10 1/11 1/12 1/13]
[ 1/5 1/6
The title pretty much says it all - for example, how would I create a
4x4 matrix whose (i,j)-th element is 1/(i+j)?
Thanks,
Alasdair

Helo Sage community,
I want to know if Sage could deal with symbolic arrays and lists (by
symbolic I mean without specifying the concrete contents of list or
array)
For example I want to solve a system of equations containing lists and
arrays like this (here A and A' are arrays; B and B' lists;

Wow, that's the best news I have heard all day!
