sgvm_perform_permute

PURPOSE ^

SGVM_PERFORM_PERMUTE perform node property permutation on MPC

SYNOPSIS ^

function mpc = sgvm_perform_permute(mpc, v, permORnmap)

DESCRIPTION ^

SGVM_PERFORM_PERMUTE perform node property permutation on MPC
   MPC = SGVM_PERFORM_PERMUTE(MPC, V, PERMORNMAP)

   Vector V is *either* PERM: a mapping that permutes *properties*
                         or
   Vector V is NMAP: a mapping of node numbers.

CROSS-REFERENCE INFORMATION ^
