说明：  实际的数值是带有符号的，即可能是正数，也可能是负数，数值的正负之分如何实现？ 通过补码表示，且用一位符号位区别其正负即可。 而数值本身可以包括整数，也可以包括小数。那么，在计算机中是如何确定小数点的位置呢？ (The actual value is unsigned, which may be positive, it may be negative, positive and negative values divided how? By complement representation, and with a bit different from the positive and negative signs can be. The value itself can include an integer, it can also include decimals. Then, the computer is how to determine the decimal place?)

双曲型方程Lax-Wendroff的差分格式程序(Matlab)，非常好的例子，具体算例，有理论分析，解题过程分析，Matlab代码，注释清晰明了，有计算结果输出和图形显示，按照Word文档说明，很快就能学会，操作简单明了，非常适合新手学习。(Lax-Wendroff hyperbolic equation difference scheme (Matlab) program, a very good example, specific examples, theoretical analysis, problem-solving process analysis, Matlab code, comments clear, with the output results and graphical display, according to the Word documentation, and soon will be able to learn, easy to understand, very suitable for beginners to learn.)

零相移滤波器m函数，优点是克服了滤波器产生的相位滞后，缺点是本仿真不能保证实时性，其原理为输入一次序列，正反各变换一遍。(Zero phase shift filter m function, the advantages of the filter to overcome the phase lag, the disadvantage is that the simulation can not guarantee real-time, the principle of the input sequence, the pros and cons of each conversion.)

基于MATLAB仿真程序，使用牛顿迭代法，在已知时延先验信息的基础上，对目标实现无源定位。 程序内还包含符号迭代和等值线绘图等角复杂代码。希望对研究无源定位的同志有所帮助。(MATLAB-based simulation program, using Newton s iterative method, the known delay on the basis of prior information on target to achieve passive positioning. Symbols within the program also includes iteration and contour drawing isometric complex code. Hope the study of passive location comrades help.)
