Functions/Subroutines | |
| subroutine | dazaxpy (n, da, dx, dy) |
| A real constant times a complex vector plus a complex vector. More... | |
| subroutine | zdgemm (transa, transb, m, n, k, alpha, a, lda, b, ldb, beta, c, ldc) |
| A real matrix multiplying a complex one, added to a complex matrix. More... | |
| subroutine blas_oct_m::dazaxpy | ( | integer, intent(in) | n, |
| real(real64), intent(in) | da, | ||
| complex(real64), intent(in), target | dx, | ||
| complex(real64), intent(inout), target | dy | ||
| ) |
A real constant times a complex vector plus a complex vector.
A real constant scales the real and imaginary parts alike, so this is daxpy over twice as many reals. The complex vectors are reinterpreted rather than copied, as transfer would.
| [in] | dx | dx(n) |
| [in,out] | dy | dy(n) |
| subroutine blas_oct_m::zdgemm | ( | character(1), intent(in) | transa, |
| character(1), intent(in) | transb, | ||
| integer, intent(in) | m, | ||

| real(real64), intent(in) | beta, | ||
| complex(real64), intent(inout), target | c, | ||
| integer, intent(in) | ldc | ||
| ) |
A real matrix multiplying a complex one, added to a complex matrix.
A real matrix multiplies the real and imaginary parts alike, so this is dgemm over matrices with twice the rows, which the caller accounts for in m, lda and ldc. As above, a and c are reinterpreted rather than copied.
| [in] | a | a(lda,ka) ka=k if transa='N' or 'n'; m otherwise |
| [in] | b | b(ldb,kb) kb=k if transa='N' or 'n'; m otherwise |
| [in,out] | c | c(ldc,n) |
