MATRIXTRACE (a)
- is any matrix.
Description
- This function shows the trace value of the given matrix.
- In , is any matirx.
- The trace of an nxn square matrix is defined to be the sum of all main diagonal entries.
- Consider the matrix A with the elements .
- Here trace of the matrix A is =.Where denotes the entry on the row and column of A.
- Now consider 3x3 matrix
- Here tr(A)= a+e+j.
