CxGenEigenAB
Advanced Analysis Library Only
AnalysisLibErrType CxGenEigenAB (void *inputMatrixA, void *inputMatrixB, ssize_t matrixSize, NIComplexNumber eigenvalues[], void *leftEigenvectors, void *rightEigenvectors);
Purpose
Computes the generalized eigenvalues, and optionally the left and/or right generalized eigenvectors, for a pair of complex matrices (A,B). The function computes the following generalized eigenproblems:
where V is the right eigenvectors matrix.
where U is the left eigenvectors matrix.
represents the generalized eigenvalues of (A,B).
Parameters
| Input | ||
| Name | Type | Description |
| inputMatrixA | void * | The input matrix A. |
| inputMatrixB | void * | The input matrix B. |
| matrixSize | ssize_t | The order of inputMatrixA and inputMatrixB. |
| Output | ||
| Name | Type | Description |
| eigenvalues | NIComplexNumber [] | The generalized eigenvalues of (inputMatrixA, inputMatrixB). |
| leftEigenvectors | void * | The left generalized eigenvectors of (inputMatrixA, inputMatrixB). If leftEigenvectors is NULL, the left generalized eigenvectors are not computed. Each column of leftEigenvectors is a left generalized eigenvector. |
| rightEigenvectors | void * | The right generalized eigenvectors of (inputMatrixA, inputMatrixB). If rightEigenvectors is NULL, the right generalized eigenvectors are not computed. Each column of rightEigenvectors is a right generalized eigenvector. |
Return Value
| Name | Type | Description |
| status | AnalysisLibErrType | A value that specifies the type of error that occurred. Refer to analysis.h for definitions of these constants. |
