AnalysisLibErrType CxDeterminant (void *inputMatrix, ssize_t matrixSize, int matrixType, NIComplexNumber *determinant);
Purpose
Calculates the complex determinant of a square, complex input matrix.
In this function you can specify the input matrix type using matrixType. The input matrix can be upper or lower triangular, general, or positive definite. For an upper or lower triangular matrix, the determinant equals the product of the diagonal elements of the matrix. For a positive definite matrix, CxDeterminant first calculates the Cholesky factorization of the input matrix and then calculates the determinant as the square of the determinant of R.
Parameters
| Input | ||||||||||||
| Name | Type | Description | ||||||||||
| inputMatrix | void * | Input complex, square matrix. The following C typedef statement defines the ComplexNum structure: typedef struct { double real; double imaginary; } ComplexNum; |
||||||||||
| matrixSize | ssize_t | Number of elements in one dimension of the input matrix. | ||||||||||
| matrixType | int | Type of the input matrix. Choose the matrix type correctly because it significantly affects the speed of computation.

| Output | ||||||||||||
| Name | Type | Description | ||||||||||
| determinant | NIComplexNumber | Complex determinant of the input matrix. The following C typedef statement defines the ComplexNum structure: typedef struct { double real; double imaginary; } ComplexNum; |

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. |
