pow_matrix_modT_pow_matrix_modPowMatrixModPowMatrixMod (Operator)

Name

pow_matrix_modT_pow_matrix_modPowMatrixModPowMatrixMod — Compute the power functions of a matrix.

Signature

Description

The operator pow_matrix_modpow_matrix_modPowMatrixModPowMatrixModPowMatrixMod computes the power of the input MatrixMatrixMatrixMatrixmatrix by a constant value. The input MatrixMatrixMatrixMatrixmatrix is given by the matrix handle MatrixIDMatrixIDMatrixIDMatrixIDmatrixID. The power value is given by the parameter PowerPowerPowerPowerpower. The input matrix is overwritten with the result. Access to the elements of the matrix is possible e.g. with the operator get_full_matrixget_full_matrixGetFullMatrixGetFullMatrixGetFullMatrix.

The type of the MatrixMatrixMatrixMatrixmatrix can be selected via MatrixTypeMatrixTypeMatrixTypeMatrixTypematrixType. The following values are supported: 'general'"general""general""general""general" for general, 'symmetric'"symmetric""symmetric""symmetric""symmetric" for symmetric, 'positive_definite'"positive_definite""positive_definite""positive_definite""positive_definite" for symmetric positive definite, 'upper_triangular'"upper_triangular""upper_triangular""upper_triangular""upper_triangular" for upper triangular, 'permuted_upper_triangular'"permuted_upper_triangular""permuted_upper_triangular""permuted_upper_triangular""permuted_upper_triangular" for permuted upper triangular, 'lower_triangular'"lower_triangular""lower_triangular""lower_triangular""lower_triangular" for lower triangular, and 'permuted_lower_triangular'"permuted_lower_triangular""permuted_lower_triangular""permuted_lower_triangular""permuted_lower_triangular" for permuted lower triangular matrices. The formula for the calculation of the result is:

Example:

Attention

For MatrixTypeMatrixTypeMatrixTypeMatrixTypematrixType = 'symmetric'"symmetric""symmetric""symmetric""symmetric", 'positive_definite'"positive_definite""positive_definite""positive_definite""positive_definite", or 'upper_triangular'"upper_triangular""upper_triangular""upper_triangular""upper_triangular" the upper triangular part of the input MatrixMatrixMatrixMatrixmatrix must contain the relevant information of the matrix. The strictly lower triangular part of the matrix is not referenced. For MatrixTypeMatrixTypeMatrixTypeMatrixTypematrixType = 'lower_triangular'"lower_triangular""lower_triangular""lower_triangular""lower_triangular" the lower triangular part of the input MatrixMatrixMatrixMatrixmatrix must contain the relevant information of the matrix. The strictly upper triangular part of the matrix is not referenced. If the referenced part of the input MatrixMatrixMatrixMatrixmatrix is not of the specified type, an exception is raised.

pow_matrix_modpow_matrix_modPowMatrixModPowMatrixModPowMatrixMod modifies the content of an already existing matrix.

Execution Information

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

This operator modifies the state of the following input parameter:

• MatrixIDMatrixIDMatrixIDMatrixIDmatrixID

Parameters

Result

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