Description

The operator pow_scalar_element_matrixpow_scalar_element_matrixPowScalarElementMatrixPowScalarElementMatrixpow_scalar_element_matrix computes the power of all elements of the input Matrix by a constant value. The input Matrix is given by the matrix handle MatrixIDMatrixIDMatrixIDmatrixIDmatrix_id. The power value Power is given by the parameter PowerPowerPowerpowerpower. A new matrix MatrixPow is generated with the result. The operator returns the matrix handle MatrixPowIDMatrixPowIDMatrixPowIDmatrixPowIDmatrix_pow_id of the matrix MatrixPow. Access to the elements of the matrix is possible e.g., with the operator get_full_matrixget_full_matrixGetFullMatrixGetFullMatrixget_full_matrix. The formula for the calculation of the result is:

Example:

PowerPowerPowerpowerpower = [2.0]

Execution Information

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.

Parameters

MatrixIDMatrixIDMatrixIDmatrixIDmatrix_id (input_control)  matrix → HMatrix, HTupleHHandleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)

Matrix handle of the input matrix.

PowerPowerPowerpowerpower (input_control)  number → HTupleUnion[int, float]HTupleHtuple (real / integer) (double / int / long) (double / Hlong) (double / Hlong)

The power.

Default: 2.0

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

MatrixPowIDMatrixPowIDMatrixPowIDmatrixPowIDmatrix_pow_id (output_control)  matrix → HMatrix, HTupleHHandleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)

Matrix handle with the raised power of the input matrix.

Result

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