用matlab实现的四类基本滤波器的设计代码，可运行(Matlab implementation of the four basic types of filter design code can be run)

格子BLOTZMANN方法的matlab程序，D2Q9模型(Lattice BLOTZMANN method matlab procedures, D2Q9 model)

Evaluate the value of an arithmetic expression in Reverse Polish Notation. Valid operators are +, -, *, /. Each operand may be an integer or another expression. Some examples: [ 2 , 1 , + , 3 , * ] -> ((2 + 1) * 3) -> 9 [ 4 , 13 , 5 , / , + ] -> (4 + (13 / 5)) -> 6 分析：这一题就是写程序计算逆波兰式的结果，遍历表达式，碰到操作数入栈，碰到操作符就从栈顶取出两个操作数，再将计算后的结果入栈，最后栈中剩余的唯一操作数就是计算结果。(.
