MB_DGER – Performs A := alpha*x*y^T + A

MB_DGER – Performs A := alphaxy^T + A

Block SymbolLicensing group: STANDARD

Function Description
The output references yX, yY and yA are always set to the corresponding input references uX, uY and uA. If HLD = on then nothing is computed otherwise the BLAS function DGER is called internally:

DGER(M, N, alpha, uX, INCX, uY, INCY, uA, LDA);

where parameters of DGER are set in the following way:

M is number of rows of the matrix referenced by uA.
N is number of columns of the matrix referenced by uA.
If the input $incx \neq 0$ then INCX is set to incx else INCX is set to $1$ .
If the input $incy \neq 0$ then INCY is set to incy else INCY is set to $1$ .
LDA is the leading dimension of matrix referenced by uA.

The error flag E is set to on if:

the reference uX or uY or uA is not defined (i.e. input uX or uY or uA is not connected),
the call of the function DGER returns error using the function XERBLA, see the system log.

See BLAS documentation [6] for more details.
