雷达模糊函数、模拟距离模糊函数，多普勒模糊函数，用多种视图显示模拟结果。(Radar ambiguity function, analogue distance ambiguity function, the Doppler ambiguity function, using a variety of view shows the simulation results.)

研究穿越沙漠的建模问题，涉及线性规划的统筹模型，适合教学使用(Studies across the desert modeling, linear programming involves co-ordination model, suitable for teaching use)

不可压缩流体的有限元快速迭代求解,是书籍的附带源代码实现(Finite Elements and Fast Iterative Solvers: with Applications in Incompressible Fluid Dynamics)

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。(. 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/After this problem is to write a program to calculate the inverse Polish results, iterate expression operand stack encounter, encounter operator to fetch two operands the stack, and then calculated as follows:> 6 Analysis- 5)) The results of the stack, the only remaining operand stack is the final calculations.)

matlab 自动生成各种随机数的命令，希望对大家有所帮助(hehe ，it is very useful to us.I hope it can give everyone a help.)

此程序主要是通过使用小波达到图像文件压缩的目的，可以比较不同的小波函数和压缩次解压缩后图像文件的差异，注意图像是二维的处理时使用二维的小波函数(This process is mainly through the use of wavelet compression to achieve the purpose of image files, you can compare different wavelet functions and extract the compressed time difference after the image file, pay attention to the handling of two-dimensional image is the use of two-dimensional wavelet function)

用于混沌时间预测一个很好的工具。可以求时间延时和时间窗。非常好用的一个预测工具(a very good software.which can make something more good.and make somebody know much)
