H_index

Purpose

cell array of indices into structure arrays for continuous element deformations

Synopsis

iced = H_index (Model,ElemData)

Description

H_INDEX cell array of indices into structure arrays for continuous element deformations
  ICED = H_INDEX (MODEL,ELEMDATA)
  the function sets up the cell array ICED of indices for continuous element deformations
  based on release information for elements of the structural model in data structure MODEL;
  the location of element releases is specified in field RELEASE of cell array ELEMDATA
  ELEMDATA{2}.RELEASE = [0;1;0] :   a flexural release is present at end i of element 2
  ELEMDATA{3}.RELEASE = [1;0;1] : an axial and a flexural release at end j of element 3
  the function supports only truss and 2d frame elements at present
