%% R8GE_RANDOM randomizes a R8GE matrix.
%
%  Discussion:
%
%    The R8GE storage format is used for a general M by N matrix.  A storage 
%    space is made for each logical entry.  The two dimensional logical
%    array is mapped to a vector, in which storage is by columns.

%
%  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.
%
%    Input, integer SEED, a seed for the random number generator.
%
%    Output, real A(M,N), the R8GE matrix.
%
%    Output, integer SEED, an updated seed for the random number generator.
