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
