AnalysisLibErrType CxTrace (void *inputMatrix, int matrixSize, int reserved, ComplexNum *trace);
Calculates the trace of a complex matrix. The trace of a matrix is the sum of all its diagonal elements.
CxTrace uses the following formula to obtain trace:
Input | ||
Name | Type | Description |
inputMatrix | numeric array | Input complex 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 | Size of inputMatrix. |
reserved | integer | Reserved parameter. |
Output | ||
Name | Type | Description |
trace | ComplexNum | Sum of the diagonal elements of inputMatrix. The following C typedef statement defines the ComplexNum structure:
typedef struct { double real; double imaginary; } ComplexNum; |
Name | Type | Description |
status | AnalysisLibErrType | A value that specifies the type of error that occurred. Refer to analysis.h for definitions of these constants. |
