compare_case

PURPOSE ^

COMPARE_CASE Compares the bus, gen, branch matrices of 2 MATPOWER cases.

SYNOPSIS ^

function compare_case(mpc1, mpc2)

DESCRIPTION ^

COMPARE_CASE  Compares the bus, gen, branch matrices of 2 MATPOWER cases.
   COMPARE_CASE(MPC1, MPC2)
   Compares the bus, branch and gen matrices of two MATPOWER cases and
   prints a summary of the differences. For each column of the matrix it
   prints the maximum of any non-zero differences.
