[Lapack] BLAS question

 ```Dear LAPACK folks, We need to compute a matrix product of the form (hc=hermitian conjugate): H = hc(M)*Q, Q = h*M where H and h are hermitian, Q is already computed (it's needed for another stage). As you can see we really need only the full upper (or lower) triangle of the product matrix, H. Looking through the BLAS routines we have not found any special routine which would be faster than the general matrix multiply of hc(M) and Q. Is there some multiply routine where we could specify only compute the full upper (or lower) triangle of the product (so as to speed things up by a bit less than a factor of 2)?

Parker assumed that Nelson would disregard the order if he (Nelson) could continue the attack and indeed supported Nelson's squadron when he saw that Nelson was pressing forward. ************************************************************************* ```
