The Mesh example has 180 resistors and 100 nodes. The description might be A1 A2 1|A1 B1 1| .. |J9 J10 1. Then the iteration might start.
Should be able to solve my problems as well. --[[User:ChristerNilsson|ChristerNilsson]] ([[User talk:ChristerNilsson|talk]]) 02:32, 20 March 2019 (UTC)
:A "spaghetti" mesh would still lead to a symmetric matrix: this does not come from the symmetry of the circuit, but from Kirchhoff's laws. If there are N nodes the matrix A has dimensions NxN, and there is a nonzero element A(i,j) for each nodes i,j linked by a resistor. To describe an arbitrary circuit, you need basically to be able to decribe an arbitrary graph: a (usually sparse) matrix, or a list of nodes together with a list of edges, for instance.
