## I4ROW_MIN returns the minimums of rows of an I4ROW.
#
#  Discussion:
#
#    An I4ROW is an M by N array of I4'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, integer X(M,N), the I4ROW.
#
#    Output, integer XMIN(M), the minimums of the rows of X.
