PLUInverse

Computes the inverse of an LU-factored general matrix AF computed by FactorizationPLURaw. LAPACK function GETRI.

Computing for type matrix<double>

bool matrix::PLUInverse(
long[]& ipiv, // pivot indices array
matrix& AI // inverse of matrix A
);

Computing for type matrix<float>

bool matrixf::PLUInverse(
long[]& ipiv, // pivot indices array
matrixf& AI // inverse of matrix A
);

Computing for type matrix<complex>

bool matrixc::PLUInverse(
long[]& ipiv, // pivot indices array
matrixc& AI // inverse of matrix A
);

Computing for type matrix<complexf>

bool matrixcf::PLUInverse(
long[]& ipiv, // pivot indices array
matrixcf& AI // inverse of matrix A
);

Parameters

ipiv

[in] Pivot indices array obtained as result of GETRF function.

[out] Inverted matrix.

Return Value

Return true if successful, otherwise false in case of an error.

Note

This method is applied to the matrix AF obtained as result of GETRF function.
