help Rec237
  ABAQUS motions (in cavity radiation analysis) output to MATLAB
  
  Syntax
      #Rec# = Fil2str('*.fil');
      #out# = Rec237(#Rec#)
 
  Description
      Read motion output from the results (*.fil) file generated from the
      ABAQUS finite element software. The asterisk (*) is replaced by the
      name of the results file. The record key for motion output is 237
      (only in ABAQUS/Standard). See section "Results file output format"
      in ABAQUS Analysis User's manual for more details.
      The following options with parameters have to be specified in the
      ABAQUS input file for the results (*.fil) file to be created and to
      contain motion results:
          ...
          *FILE FORMAT, ASCII
          *NODE FILE
          MOT
          ...
      NOTE: The results file (*.fil) must be placed in the same directory
      with the MATLAB source files in order to be processed.
      
  Input parameters
      #Rec# (string) is an one-row string containing the ASCII code of the
          ABAQUS results (*.fil) file. It is generated by the function
          Fil2str.m.
  
  Output parameters
      #out# ([#n# x #m#]) is a double array containing the attributes of
          the record key 237 as follows:
          Column  1  –  Node number. 
          Column  2  –  First component of motion. 
          Column  3  –  Second component of motion.
          Column  4  –  Etc
          where #n# is the number of nodes multiplied by the number of
          increments and #m#-1 is the number of components of motion per
          node. If the results file does not contain the desired output,
          #out# will be an empty array
