netlab工具包，包含许多matlab图像处理等开发函数，解压到安装目录toolbox文件夹下，在matlab里更新路径后可直接调用(netlab Kit contains many matlab image processing development function, extract to the installation directory Toolbox folder in matlab can be called directly after the update path)

Digital signal processing is the important aspect of modern communication system. here is the matlab code given which helps for the beginers for understanding the basics of DSP.

说明：  用Hilbert-Huang变换进行脑电信号处理可以细致的看到脑电信号的频率变化规律。 (With the Hilbert-Huang Transform EEG signal processing can see detailed changes of the frequency of EEG.)

wifi无线物理层密钥生成，通过RSS进行提取，之后进行密钥生成，最后计算误码率。(wifi wireless physical layer key generation, extraction via RSS, after key generation, the final calculation of the error rate.)

利用Peng-Robinson方程计算纯质R32p—T相图(Peng-Robinson equation using pure R32p-T phase diagram)

在matlab下编程使用jacket工具包进行GPU加速图像平滑算法，对900×900的图像平滑可达8倍多的加速比。需要jacket工具包及cuda toolkit。(In matlab programming toolkit used jacket GPU-accelerated image smoothing algorithm, the 900,900 image smooth acceleration up to 8 times more than that. Need jacket toolkit and cuda toolkit.)

Escribir un programa que calcule el polinomio de interpolacion de lagrange de una funcion en unos puntos dados mediante la formula de newton,y que permite añ adir nuevos puntos de interpolacion,dibujar la funcion y el polinomio de interpolacion obtenido,hacer una version que sirva para interpolar los valores de una tabla dibujando,en este caso solo en el polinomio de interpolacion.
