What is Matrix Trace?

In linear algebra, the trace of a square matrix is the sum of the elements on the main diagonal (from the upper left to the lower right).

For a square matrix $$A$$, the trace $$Tr(A)$$ is calculated as:

$$ Tr(A) = \sum_{i=1}^{n} a_{ii} $$

Where $$a_{ii}$$ are the diagonal elements of the matrix $$A$$.

The trace is only defined for square matrices. It has various applications in linear algebra, statistics, and other areas of mathematics.

Example

For the matrix:

123
456
789

The trace is 1 + 5 + 9 = 15.
