`Condense_MV`

## Purpose

condense matrix Kf and vector Pf to a reduced set idr of degrees of freedom

## Synopsis

`[Kfc,Pfc] = Condense_MV (Kf,idr,Pf)`

## Description

CONDENSE_MV condense matrix Kf and vector Pf to a reduced set idr of degrees of freedom [KFC,PFC] = CONDENSE_MV (KF,IDR,PF) function condenses free dof stiffness matrix KF and applied force vector PF to a reduced set of dofs as specified in list or row vector IDR; the condensed stiffness matrix is KFC and the initial force vector is PFC
