I will do that.  Thanks for your help.

Another possible change would be to replace the 'const
vsip::Matrix<...>' by 'vsip::const_Matrix<...>'. Note that VSIPL++
promotes passing view types (such as Matrix<>) by value, so the const
qualifier isn't really very meaningful. Instead, use 'const_Matrix<>' to
convey that its content is to be immutable.

Using the above operator() notation on const_Matrix<> will work as
expected, too.

Thanks,
