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.

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.

trace(matrix)

trace(`[[3;1;0];[3;2;1];[4;1;7]]`), returns 12
