AnalysisLibErrType CxGenInvMatrix (void *inputMatrix, int matrixSize, int matrixType, void *matrixInverse);
Calculates the inverse of a complex, square input matrix. If B denotes the inverse of the matrix A, then
AB = I
where I is the identity matrix
The input matrix can be an upper or lower triangular matrix, a general, square matrix, or a positive definite matrix. You can save significant computation time if you properly specify the input matrix type.
Input | ||||||||||||
Name | Type | Description | ||||||||||
inputMatrix | numeric array | Input complex, square matrix. This
matrix must be an array of ComplexNum. The following C typedef statement defines the ComplexNum structure: typedef struct { double real; double imaginary; } ComplexNum; |
||||||||||
matrixSize | integer | Number of elements in one dimension of the matrix. | ||||||||||
matrixType | integer | Type of the input matrix. Choose the matrix type correctly because it significantly affects the speed of computation. The following table shows valid matrix type values.
