#### Description :

The calculator provides a way to calculate online the trace of a square matrix. The trace of a square matrix is ​​equal to the sum of the terms of its diagonal. The matrix calculator can calculate the trace with letters or numbers.

# Calculation of the trace of a square matrix

The calculator calculates the trace of a matrix with the results in exact form : to calculate the trace of the following matrix ((3,3,4),(1,2,0),(0,1,7)), enter trace([[3;1;0];[3;2;1];[4;0;7]]), at the end of the calculations, the response is returned.

The calculator allows symbolic calculations, it is possible to use letters: to calculate the trace of a matrix like this : ((a,3*a,4),(1,2*a,0),(0,c,a/2)), type trace([[a;1;0];[3a;2a;c];[4;0;a/2]]), after calculation, the result is returned.
