Trace is a concept in linear algebra that is an important tool to determine the properties of matrices. It is defined as the sum of the diagonal entries of a matrix. In other words, the trace of a matrix is the sum of all its eigenvalues. The trace of a matrix is often a crucial tool in various areas of mathematics such as calculus, differential geometry, physics, and signal processing. In this article, we will discuss the properties of the trace, its importance, and applications in different fields.
