Hi, I'm trying to get a while cycle which checks convergence every iteration.
Within the cycle, I'm solving a system which returns each iteration 3 types of solutions: a (vector), B, C (matrices).
Subscript "0" is related to the (l-1) iteraton, the other refers to the (l) iteration.
I wrote this code:
while (abs(a_0-a) > 1e-6) & (abs(B_0-B) > 1e-6) & (abs(C_0-C) > 1e-6)
It starts, but it do only one iteration, I don't know why.
It should iterate until ALL residues are lower than 1e-6.
Probably it's wrong, maybe due to parentheses or logical operators. I've already tried to change them, but in the other cases it doesn't work.
What should I do?
Thank you for your help!!
