TīmeklisHere is what I must do : I have to generate a matrix using do i=1,n x (i) = i*i*1.0D+00 do j=1,n A (i,j) = (i+j)*j*1.00D+00 end do end do and then simply multiply Matrix A by Vector x (b=Ax). For Lapack, I simply use CALL DGEMV ('N',n,n,1.0D+00,a,n,x,1,0.0D+00,b,1) How do I achieve this in PBLAS?
