Definition

A linear-algebra approach that represents multiplication by coordinate functions on the quotient algebra R/I (where I is an ideal) as finite matrices relative to a chosen basis; eigenstructure of these multiplication matrices encodes the coordinates and multiplicities of the common zeros of the ideal when the quotient is finite-dimensional.
