how to create Matlab code for fault?

Hi, does anybody know how to create a fault using matlab code?

[John D'Errico]

What is a fault? Something deep under the surface of the earth? Something psychological? Something else?

You need to explain your question. As it is, this is impossible to even try to answer.
