If a 2 x 2 real matrix has zero trace, its square is a diagonal matrix. The trace of a 2 × 2 complex matrix is used to classify Möbius transformations. First, the matrix is normalized to make its determinant equal to one. Then, if the square of the trace is 4, the corresponding transformation is parabolic.
It has a compatibility mode with Maple, Derive and MuPAD software and TI-89, TI-92 and Voyage 200 calculators. The system was chosen by Hewlett-Packard as the CAS for their HP Prime calculator, which utilizes the Giac/Xcas 1.1.2 engine under a dual-license scheme.
When L/K is separable, the trace provides a duality theory via the trace form: the map from L × L to K sending (x, y) to Tr L/K (xy) is a nondegenerate, symmetric bilinear form called the trace form. If L/K is a Galois extension, the trace form is invariant with respect to the Galois group.

O-Matrix is a proprietary licensed matrix programming language for mathematics, engineering, science, and financial analysis.
A trace diagram representing the adjugate of a matrix. In mathematics, trace diagrams are a graphical means of performing computations in linear and multilinear algebra. They can be represented as (slightly modified) graphs in which some edges are labeled by matrices. The simplest trace diagrams represent the trace and determinant of a matrix.
Not every square matrix is similar to a companion matrix, but every square matrix is similar to a block diagonal matrix made of companion matrices. If we also demand that the polynomial of each diagonal block divides the next one, they are uniquely determined by A , and this gives the rational canonical form of A .
The colors of the calculator are still the same as those of the TI-Nspire models; the CX is white and dark blue, while the CX CAS is gray and black. The external connectors have changed slightly. The mini-USB port, located at the center on the top of the TI-Nspire series, has moved to the right on the top on the CX series.
One can show that the trace-norm is a norm on the space of all trace class operators () and that (), with the trace-norm, becomes a Banach space. When H {\displaystyle H} is finite-dimensional, every (positive) operator is trace class and this definition of trace of A {\displaystyle A} coincides with the definition of the trace of a matrix .
