Simulation of Speech Enhancement using Spectral Subtraction

用matlab实现概率方面的编程，包括随机数的生成函数方面知识(Probability with matlab implementation aspects of programming, including random number generation function of knowledge)

L-system and IFS are used to the plant s simulation. In this package the theories of L-system and IFS were concisely described. The excellence and short of constructing Fractal image with L-system or IFS were discussed. So a method was put forward in this package. At last the three-dimension tree model ceatrs successfully based on L-system and IFS.
