#
## R8ROW_INDICATOR sets up an indicator R8ROW.
#
#  Discussion:
#
#    An R8ROW is an M by N array of R8's, regarded as an array of M rows,
#    each of length N.
#
#    The value of each entry suggests its location, as in:
#
#      11  12  13  14
#      21  22  23  24
#      31  32  33  34

#
#  Parameters:
#
#    Input, integer M, the number of rows of the matrix.
#    M must be positive.
#
#    Input, integer N, the number of columns of the matrix.
#    N must be positive.
#
#    Output, real A(M,N), the indicator table.
