I am working with set of differential equations, where I need repeated iterations. I need to number the steps as double or triple index /suffixes. I would like to know how to do it.
Not sure if I understand your question, but probably you are referring to, for example, this:
for i=1:n
for j=1:n
A(i,j) = C(1,i)+D(2,j)
end
end
are you trying to find out how to sequence the set of pairs or triples? that is, find a linear ordering on all {[i,j] | 0
Thanks Friends,
I have to refer many indices like b[i, j], w[m,n], k[i], y[j]. but I don't know how to apply it in Mathematica programs. Please help me if you can.
If you are actually asking about the notation you need to use that is double square brackets.
For example if you have a 2 dimensional list named K, the (i,j)-th element will be K[[i,j]]. K[[i]] gives the whole i-th row (same as K[[i,All]]), while K[[All,j]] gives the whole j-th column.

If what you are asking is something else, please clarify it a little bit.
