详细阐述了波特沃斯低通滤波器的matlab仿真原理及对应的c语言实现过程，读完此资料后，对于巴特沃斯低通滤波器不管从c语言实现还是matlab实现，你都会有很好的理解(Matlab simulation principles elaborated Porter Worth low-pass filter and the corresponding c language implementation process, after reading this information, for Butterworth low-pass filter regardless of language or a c matlab implementation, you will have a very good understanding)

一个关于多目标优化算法的程序，并有说明资料(A multi-objective optimization algorithm on the program, and descriptive information)

An item that has an integer label.

说明：  图像变换 matlab语言编辑 包括灰度、旋转、放大、镜像(Image transformation)

一天征服傅里叶变换，对傅里叶变换做了浅显易懂的分析，对学习数字信号处理有帮助。(One day conquer the Fourier transform, made accessible for the Fourier transform analysis, is helpful to study digital signal processing.)

该算法既保留了遗传算法的搜索特性，又利用了免疫算法的多机制求解多目标函数最优解的自适应特性，在很大程度上避免了“早熟”，收敛于局部极值。 生物体的免疫系统是一个高度进化、复杂的系统，它能自适应地识别和排除入侵肌体的抗原性异物，保护机体免受损害及维持内坏境稳定，并具有学习、记忆和自适应调节的能力。当抗原入侵时，免疫系统通过自体耐受对‘自己’和‘非己’进行识别，并产生最恰当的抗体排除抗原，通过抗体与抗体之间、抗原与抗体之间的相互刺激和抑制关系，降低抗原对免疫细胞的刺激，抑制抗体的过度分化、增殖，保证免疫平衡并维持抗体的多样性。同时在免疫过程中将产生抗体的部分细胞作为记忆细胞保存下来，对于今后侵入的同类抗原，相应的记忆细胞受到激发而产生大量的抗体。为提高生物体的免疫机能，医学上往往根据抗原性异物提取疫苗给生物体接种，接种过的生物体由于免疫细胞预先获得了抗原染色体的特征信息，因而在类似抗原入侵时，能迅速产生亲和度很高的抗体，有效抵御入侵。(The search algorithm only retains the characteristics of genetic algorithms, and use multiple mechanisms of immune algorithm for solving multi-objective characteristics of adaptive optimal solutions, in large part to avoid the " premature" , converge to local minima. Organism' s immune system is a highly evolved, complex system which adaptively identify and remove foreign matter intrusion antigenic body, protecting the body injury and maintain internal stability bad environment, and has learning, memory and adaptive Ability. When the antigen invasion of immune system tolerance to autologous ' own' and ' non-self' to identify and produce the most appropriate antigen antibody excluded by between antibody and antibody, antigen and antibody mutual stimulation and inhibition of the relationship between reduce the antigen to stimulate immune cells, antibodies inhibit excessive differentiation, proliferation, immune balance and ensure the maintenance of antibody dive)

MATLAB混合编程想把matlab强大的功能用在自己的工程实践中吗这是本不错的混合编程的书(Hybrid Programming MATLAB want matlab powerful in their own practice, it works this is a mixture of good programming book)

一个非线性滤波器的实现程序，能够实现其基本的功能，对于初学者很有帮助。(A nonlinear filter is implemented procedures to achieve its basic functionality, useful for beginners.)

In factor analysis rotations of the loadings are very often applied, whereas in chemometrics these methods are very seldom used. This is in spite of the fact that it is possible to obtain better conditions for interpretation of PCA models on complex data. I here provide an algorithm by which it is possible to apply rotations from the Orthomax family (quartimax and varimax) to a PCA-model.
