r = Matrices.trace(A);
This function computes the trace, i.e., the sum of the elements in the diagonal of matrix A.
A = [1, 3;
2, 1];
r = trace(A);
results in:
r = 2.0
function trace extends Modelica.Icons.Function; input Real A[:, size(A, 1)] "Square matrix A"; output Real result "Trace of A"; end trace;
