For example, microprocessor x2 has membership 0.5 with respect to microprocessor x1. Note that if these values were arranged into a matrix, it would not be symmetric. These membership values do not express similarity or relation; they represent membership values of ordering when considered in a particular order. If we now employ Equation (9.5) to calculate all of the relativity values, the matrix shown below expresses these calculations; this is the so-called comparison, or C, matrix. In the notation for the relativity values, we have f(x i |xj) = f(ith row|jth column). For example
