Various mathematical tools in matlab

说明：  设计低通IIR滤波器；并将此低通滤波器映射为高通、带通或带阻滤波器。并验证变换后的滤波器是否满足指标。并求输入x(n)=[cos(w1n)+cos(w2n)]u(n)经过系统后的输出y(n)(Low-pass IIR filter design and mapping this low-pass filter high pass, band pass or band stop filter. And verify whether the filter transformation to meet the target. And to seek input x (n) = [cos (w1n)+ cos (w2n)] u (n) through the system output after the y (n))

使用matlab环境的GUI工具仿真八段均衡器，可视化界面，频域响应分析。(A case study of 8-band Equlizer in matlab by GUI tool)

说明：  单点坐标转换本地区的matlab拟合单点坐标转换本地区的matlab拟合(The single point coordinate transformation in the matlab fitting)

To encode a binary data using runlength encoding with setting the count buffer to limit to a required datatype size value. If image use reahape to make it to row.

One of the most popular adaptive algorithms available in the literature is the stochastic gradient algorithm also called least-mean-square (LMS) [1], [2]. Its popularity comes from the fact that it is very simple to be implemented. As a consequence, the LMS algorithm is widely used in many applications

直接扩频系统常用函数，有助于对直接扩频系统的算法研究。(functions for Direct spread spectrum system,guod referense for the study for Direct spread spectrum system)

This package was used was aircraft landing simulation. Its code implements algorithms, that detect objects on planes runway: vehicles, people, animals. Analizes black&white image from infrared camera (folder containes just Photoshop images), detects objects, highlights them and informs pilot of possible risks.
