function isok = print_x( matname, X )

%{
-----------------------------------------------------------
  This function prints into file the contents of full matrix M.

  isok = print_vec(matname, X)

  Inputs:
  matname     The name of the generated file
  X           The full matrix to be printed

  Outputs:
  isok        This will be -1 if any of the file operations failed

  The resulting file is created in the working directory.
