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

Block SymbolLicensing group: STANDARD
PIC

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}"A", {2}"U" and {3}"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 [7] for more details.
