MB_DGER – Performs A := alpha*x*y^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 0 then INCX is set to incx else INCX is set to 1.
- If the input incy 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 [9] for more details.
This block does not propagate the signal quality. More information can be found in the 1.4 section.
