function value = r8vec_product ( n, a )

%*****************************************************************************80
%
%% R8VEC_PRODUCT returns the product of the entries of an R8VEC.
%
%  Discussion:
%
%    In FORTRAN90, this facility is offered by the built in
%    PRODUCT function:
%
%      VEC_PRODUCT ( N, A ) = PRODUCT ( A(1:N) )
%
%    In MATLAB, this facility is offered by the built in
%    PROD function:
%
%      VEC_PRODUCT ( N, A ) = PROD ( A(1:N) )
