[Control systems]

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

[Economics]

A number derived from the values of the elements of a square matrix. For example, if

*a*

*are the elements in the*

_{ij}*i*th row and

*j*th column of a 2 * 2 matrix, its determinant is given by Δ =

*a*

_{11}

*a*

_{22}-

*a*

_{12}

*a*

_{21}; 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 a

_{11}/a

_{12}= a

_{21}/a

_{22}, Δ = 0.
