#
## R8ROW_MAX returns the maximums of rows of an R8ROW.
#
#  Discussion:
#
#    An R8ROW is an M by N array of R8's, regarded as an array of M rows,
#    each of length N.

#
#  Parameters:
#
#    Input, integer M, N, the number of rows and columns in the array.
#
#    Input, real X(M,N), the R8ROW.
#
#    Output, real XMAX(M), the maximums of the rows of X.
