determinant A mathematical object that is useful in the analysis and solution of systems of linear equations. The determinant of a square matrix, which may represent a set of linear equations, is a number that reveals important properties of the matrix. For example, if the matrix represents a two-dimensional transformation, its determinant gives the ratio by which areas have been changed.
