  This function prints into file the contents of full vector v.

  isok = print_vec(vecname, v)

  Inputs:
  vecname     The name of the generated file
  v           The full vector (column or row) 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.
