scale_matrixScaleMatrixScaleMatrixscale_matrixT_scale_matrix🔗

Short description🔗

scale_matrixScaleMatrixScaleMatrixscale_matrixT_scale_matrix — Scale a matrix.

Signature🔗

scale_matrix( matrix MatrixID, number Factor, out matrix MatrixScaledID )

Description🔗

The operator scale_matrixScaleMatrix scales the Matrix by a constant factor. The matrix is defined by the matrix handle MatrixIDmatrixIDmatrix_id. A new matrix MatrixScaled is generated with the result. The operator returns the matrix handle MatrixScaledIDmatrixScaledIDmatrix_scaled_id. Access to the elements of the matrix is possible e.g., with the operator get_full_matrixGetFullMatrix. The formula for the calculation of the result is:

\[\begin{eqnarray*} \texttt{MatrixScaled}_{ij} \quad = \quad \textrm{Factor} \quad \cdot \quad \texttt{Matrix}_{ij}. \end{eqnarray*}\]

Example:

Factorfactorfactor = 1.51.5

\[\begin{eqnarray*} \texttt{Matrix} = \left[ \begin{array}{rrr} 3.0 & 1.0 & -2.0 \\ -2.0 & 6.0 & 2.0 \\ -5.0 & -4.0 & 1.0 \end{array} \right] \end{eqnarray*}\]

\[\begin{eqnarray*} \qquad \to \qquad \texttt{MatrixScaled} = \left[ \begin{array}{rrr} 4.5 & 1.5 & -3.0 \\ -3.0 & 9.0 & 3.0 \\ -7.5 & -6.0 & 1.5 \end{array} \right] \end{eqnarray*}\]

Processed without parallelization.

Parameters🔗

MatrixIDmatrixIDmatrix_id (input_control) matrix → (handle)HTuple (HHandle)HMatrix, HTuple (IntPtr)HHandleHtuple (handle)

Matrix handle of the input matrix.

Factorfactorfactor (input_control) number → (real / integer)HTuple (double / Hlong)HTuple (double / int / long)Union[int, float]Htuple (double / Hlong)

Scale factor.

Default: 2.02.0
Suggested values: 0.1, 0.2, 0.3, 0.5, 0.7, 1.0, 1.5, 2.0, 3.0, 5.0, 10.0

Matrix handle with the scaled elements.

Result🔗

If the parameters are valid, the operator scale_matrixScaleMatrix returns the value 2 (H_MSG_TRUE). If necessary, an exception is raised.
