MX_DTRNSQ – Square matrix in-place transposition: A := alpha*A^T

Block SymbolLicensing group: STANDARD

Function Description
The function block MX_DTRNSQ transpose the scalar multiple of the square matrix referenced by uA in-place.

The output reference yA is always set to the corresponding input references uA. If HLD = on then nothing else is done otherwise the BLAS-like function X_DTRNSQ is called internally:

X_DTRNSQ(N, ALPHA, uA, LDA);

where parameters of X_DTRNSQ are set in the following way:

N is number of rows and columns of the matrix referenced by uA.
If the input alpha is equal to 0 then ALPHA is set to 1 else ALPHA is set to alpha.
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),
the matrix referenced by uA is not square,
the call of the function X_DTRNSQ returns error using the function XERBLA, see the system log.

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

Input

uA	Input reference to matrix A	Reference
alpha	Scalar coefficient alpha	Double (F64)
