[Control systems]
The product of the partial return differences associated with the nodes of a signal-flow graph.

A number derived from the values of the elements of a square matrix. For example, if aij are the elements in the ith row and jth column of a 2 * 2 matrix, its determinant is given by Δ = a11 a22 -a12 a21 ; the derivation of determinants for larger matrices is similar in principle. A major function of determinants is to check whether the rows or columns of a matrix are independent; if they are not independent then the determinant is zero. It can be seen that if a11 /a12 = a21 /a22, Δ = 0.
