help Rec1901
  ABAQUS node definition output to MATLAB
  
  Syntax
      #Rec# = Fil2str('*.fil');
      #out# = Rec1901(#Rec#)
 
  Description
      Read node definition 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 node definition
      output is 1901. See section "Results file output format" in ABAQUS
      Analysis User's manual for more details.
      The following option with parameter has to be specified in the ABAQUS
      input file for the results (*.fil) file to be created:
          ...
          *FILE FORMAT, ASCII
          ...
      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 1901 as follows:
          Column  1  –  Node number. 
          Column  2  –  First coordinate.
          Column  3  –  Second coordinate.
          Column  4  –  etc.
          where #n# is the number of nodes and #m#-1 is the number of
          coordinates per node. If the results file does not contain the
          desired output, #out# will be an empty array
