Syntax

  r = Matrices.trace(A);

Description

This function computes the trace, i.e., the sum of the elements in the diagonal of matrix A.

Example

  A = [1, 3;
       2, 1];
  r = trace(A);

  results in:

  r = 2.0

result = trace(A)

A	Type: Real[:,size(A, 1)] Description: Square matrix A

result	Type: Real Description: Trace of A
