Sparse Matrix Homework

Solve the equations for an electrical circuit consisting of only resistive elements.

Data Files

In each data file:
(i) first line gives number of branches and number of loops in the circuit;
(ii) subsequent lines have the format:
1. Branch number
2. Numbers of the two nodes that the branch connects
3. Numbers of the loops on the left and right sides of branch
    ---orientation is from 1st node to 2nd
4. Resistance of the branch
5. Applied voltage drop along the oriented branch.
