AnalysisLibErrType Trace (void *inputMatrix, int matrixSize, double *trace);
Finds the trace of the 2D input matrix. The trace is the sum of the matrix elements along the main diagonal. Trace obtains the trace using the following formula:
The input matrix must be a matrixSize-by-matrixSize square matrix.
