# Matrix trace calculator

Trace of square matrix is the sum of diagonal elements of this matrix:

tr(
A ) =
a_{1,1} +
a_{2,2} + ... +
a_{i,i} + ... +
a_{n,n}

This calculator *finds trace of square matrix* with step by step solution. As matrix elements
one can input not only numbers and fractions but also the parameters.

## Input matrix dimension

Matrix dimension:A = |
