Lagrange插值、Newton插值函数等插值函数，函数为数值分析课本上的例题。(Lagrange interpolation, Newton interpolation function, such as interpolation function, function for the numerical analysis of the textbooks on the sample questions.)

按照给定指标采用模拟低通滤波器（巴特沃思低通）去逼近理想模拟低通滤波器 ，然后通过双线性变换法对模拟滤波器进行数字化，得到数字滤波器 。(Indicators in accordance with a given analog low-pass filter (Butterworth low-pass) to approximate the ideal analog low-pass filter, and then through the bilinear transformation method of digitizing analog filters, the digital filter.)

说明：  这是语音信号处理里面的，基本谱减法，处理的效果很不错，很适合初学者研究！(This is the speech signal processing inside the basic spectral subtraction to deal with the effect of very good, very suitable for beginners study!)

说明：  这是一部matlab的教材，比较基础，适合初学者，不知道有没有人上传，先发一下，如果有劳请版主删掉！(It is a matlab materials, basis of comparison, for beginners, do not know if anyone upload, start that, if there are moderators, please delete labor!)

Matlab trgonometric function,there are 4 examples,hope to use everyone.(Matlab trgonometric function, there are 4 examples, hope to use everyone.)

说明：  在考虑汽车零部件包装箱长、宽、高等三维尺寸的约束下，以配送中心为原点，分派多辆同一规格的货车到n个供应商处取货，最后回到配送中心。本章所构建的三维装载约束下的汽车零部件循环取货路径优化模型要解决的问题是确定循环取货路径，要求充分考虑汽车零部件在货车车厢中的三维装载位置，确保每个供应商处的零部件均能成功装载，尽可能使车辆装载率最大，且所有车辆的总行驶路径最短。(In considering the auto parts box length, width, higher dimensional size constraints to the distribution center as the origin, a multi-vehicle dispatch trucks to the same specifications of the pick n suppliers, and finally back to the distribution center. Auto Parts Pick cycle path constructed three-dimensional loading constraints under chapter optimization model to solve the problem is to determine the circulation pickup path requires full consideration in boxcars loaded in three-dimensional position of auto parts, to ensure that each vendor Parts can successfully loaded, as the vehicle maximum loading rate, and the total of all vehicles traveling the shortest route.)

M/N逻辑法航迹起始程序，仿真环境参照《雷达数据处理及应用》P99页，程序简单明了，适合初学者(M/N logic method of track initiation procedures, simulation environment reference radar data processing and application P99 page, the procedure is simple and clear, suitable for beginners)
