%% r8row_min() returns the minimums 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.

%
%  Input:
%
%    integer M, N, the number of rows and columns in the array.
%
%    real X(M,N), the R8ROW matrix.
%
%  Output:
%
%    real XMIN(M), the minimums of the rows of X.
%
%    integer IXMIN(M); IXMIN(I) is the column of X in which
%    the minimum for row I occurs.
