ML_DLACPY – Copies all or part of one matrix to another matrix

Block SymbolLicensing group: STANDARD

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

DLACPY(sUPLO, M, N, uA, LDA, uB, LDA);

where parameters of DLACPY 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 number of rows of the matrix referenced by uB is set to M and the leading dimension of the matrix referenced by uB is set to LDA

The error flag E is set to on if:

the reference uA or uB is not defined (i.e. input uA or uB is not connected),
the allocated number of elements of the matrix referenced by uA is different from the allocated number of elements of the matrix referenced by uB.

See LAPACK documentation [8] for more details.
