LDRitzVectors

Purpose

generation of mass and stiffness orthogonal Load Dependent Ritz vectors

Synopsis

[LDR,omega] = LDRitzVectors (Kf,M,Pref,nov)

Description

LDRITZVECTORS generation of mass and stiffness orthogonal Load Dependent Ritz vectors
  generation of nov Load Dependent Ritz vectors that are orthonormal to
  the lumped mass matrix M and orthogonal to the stiffenss matrix Kf
  INPUT -----------------------------
  Kf   : nf x nf stiffness matrix
  M    : mass matrix or lumped mass vector
  Pref : vector of applied force distribution 
  nov  : number of Load Dependent Ritz vectors
  OUTPUT ----------------------------
  LDR   : Load-Dependent Ritz vectors
  omega : eigenfrequencies of reduced problem
