4 Derivative in a trace Recall (as in Old and New Matrix Algebra Useful for Statistics) that we can define the differential of a function f(x) to be the part of f(x + dx) − f(x) that is linear in dx, i.e. is a constant times dx. Then, for example, for a vector valued function …

(The trace of a square matrix is the sum of the diagonal elements.) Then the eigenvalues are found by using the quadratic formula, as usual.

Trace (linear algebra) For other uses, see Trace In linear algebra, the trace of an n -by- n square matrix A is defined to be the sum of the elements on the main diagonal (the diagonal from the upper left to the lower right) of A, i.e., where aii represents the entry on the i th row and i th column of A.

The trace is a linear mapping.

In linear algebra, the trace (often abbreviated to tr) of a square matrix A is defined to be the sum of elements on the main diagonal (from the upper left to the lower right) of A. The trace of a matrix is the sum of its (complex) eigenvalues, and it is invariant with respect to a change of basis.
