A new calculation for boolean derivative using cheng product

The matrix expression and relationships among several definitions of boolean derivatives are given by using the cheng product. we introduce several definitions of boolean derivatives. by using the cheng product,the matrix expressions of boolean derivative are given,respectively. furthermore,the relationships among different definitions are presented. the logical calculation is converted into matrix product. this helps to extend the application of boolean derivative. at last,an example is given to illustrate the main results. © 2012 hao chen and jitao sun.
