图像水平变换：分别实现对图像的水平外凹和水平外凸。(Image level of transformation: the implementation level of the image and level .)

是一些利用小波变换进行多源图像融合的程序 (Some wavelet transform image fusion process)

说明：  讲解数字PID很好的电子书，里面有现成的matlab源码，比较实用。(Digital PID on a good e-books, there are ready-made source matlab, more practical.)

用DFT近似计算连续时间周期信号的频谱，对matlab新手适用。(Approximate calculation using DFT spectrum of continuous-time periodic signal of matlab novice apply.)

多层感知神经网络对SI发动机逼近训练,对20000组真实数据进行训练，画出仿真图(trainning net for SI enine)

说明：  利用MATLAB语言编写的直流电动机制动特性分析的程序(The use of MATLAB language of DC motor braking characteristics of process)

考虑一个线性自适应均衡器的原理方框图如《现代数字信号处理导论》p.275自适应均衡器应用示意图。用LMS算法实现这个自适应均衡器，画出一次实验的误差平方的收敛曲线，给出最后设计滤波器系数。一次实验的训练序列长度为500。进行20次独立实验，画出误差平方的收敛曲线。给出3个步长值的比较。(consider a linear adaptive equalizer block diagram as the principle of "modern digital signal processing" Introduction to the p.275 adaptive equalizer application schema. LMS algorithm with the adaptive equalizer, painted a square experimental error of convergence curve, given final design filter coefficients. Experimental a length of the training sequence to 500. Conduct 20 separate experiments, painted square error of the convergence curve. Given three step-value comparisons.)

这是胡不变矩的经典matlab程序，其实就是不变矩的验证，七阶矩.(This is the classic Hu invariant moments matlab program, in fact, the same moment the validation, seven-order moments.)

里面是一个matlab的程序是设计FIR滤波器的 里面有 实际的代码 (There is a matlab procedure is to design FIR filters there are the actual code)
