#
## R8ROW_TO_R8VEC converts an R8ROW into an R8VEC.
#
#  Discussion:
#
#    An R8ROW is an M by N array of R8's, regarded as an array of M rows,
#    each of length N.
#
#  Example:
#
#    M = 3, N = 4
#
#    A =
#      11 12 13 14
#      21 22 23 24
#      31 32 33 34
#
#    X = ( 11, 12, 13, 14, 21, 22, 23, 24, 31, 32, 33, 34 )

#
#  Parameters:
#
#    Input, integer M, N, the number of rows and columns.
#
#    Input, real A(M,N), the R8ROW.
#
#    Output, real X(M*N), a vector containing the M rows of A.
