ML_DLASET – Initilizes the off-diagonal elements and the diagonal elements of a matrix to given values

Block SymbolLicensing group: STANDARD

Function Description
The output reference yA is always set to the corresponding input references uA. If HLD = on then nothing is computed otherwise the LAPACK function DLASET is called internally:

DLASET(sUPLO, M, N, alpha, beta,uA, LDA);

where parameters of DLASET are set in the following way:

Integer input uplo is mapped to the string sUPLO: ${0, 1} \to "A"$ , ${2} \to "U"$ and ${3} \to "L"$ .
M is number of rows of the matrix referenced by uA.
N is number of columns of the matrix referenced by uA.
LDA is the leading dimension of the matrix referenced by uA.

The error flag E is set to on if:

the reference uA is not defined (i.e. input uA is not connected).

See LAPACK documentation [10] for more details.

This block does not propagate the signal quality. More information can be found in the 1.4 section.
