Advanced Analysis Library Only
AnalysisLibErrType Trace (void *inputMatrix, ssize_t matrixSize, double *trace);
Purpose
Computes the trace of a real 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.
