Hello, 

Thanks for your email.  The upper bound is out-of-range to demonstrate
the range-checking error handling (described in the subsequent paragraph).

  Here is the output from the program.  The final loop attempts to read
  outside the range of the matrix `m', and the error is trapped by the
  range-checking code in `gsl_matrix_get'.

       $ ./a.out
       m(0,0) = 0.23
       m(0,1) = 1.23
       m(0,2) = 2.23
       m(1,0) = 100.23
       m(1,1) = 101.23
       m(1,2) = 102.23
       ...
       m(9,2) = 902.23
       gsl: matrix_source.c:13: ERROR: first index out of range
       Default GSL error handler invoked.
