Ks_matrix

Purpose

block diagonal matrix of basic element stiffness matrices for structural model

Synopsis

Ks = Ks_matrix (Model,ElemData)

Description

KS_MATRIX block diagonal matrix of basic element stiffness matrices for structural model
  KS = KS_MATRIX (MODEL,ELEMDATA)
  the function sets up the block diagonal matrix of basic element stiffness matrices KS
  for the structural model specified in data structure MODEL with element property
  information in cell array ELEMDATA
