MATLAB语言工具箱-TOOLBOX实用指南 涉及科学算法，自动控制，信号处理，神经网络等多科学领域。(Toolbox MATLAB language-TOOLBOX Practical Guide for scientific algorithms, automatic control, signal processing, neural networks and other fields of science.)

说明：  径向基函数神经网络（RBF）的MATLAB程序，比较详细，希望对学习RBF的人有帮助(Radial basis function neural network (RBF) of the MATLAB program, a more detailed study RBF people who want to help)

可用于数字信号处理中使用MATLAB设计的学习的四个实验,包括了FIR，IIR，FFT的设计学习(Can be used for digital signal processing designed to learning MATLAB four experiments, including FIR, IIR, FFT design study)

基于MATLAB的时域信号采样及频谱分析，实现过程及代码(MATLAB-based time-domain signal sampling and spectral analysis, implementation process and the code)

仿真QPSK，包含源程序，调制，解调过程也有，仅供参考。(simulationQPSK)

数字图像在产生过程中经常会受到噪音污染。因此，对于数字图像应该对其进行去噪音处理。在传统的基于傅里叶变换的信号去噪音方法中，可以使得信号和噪音的频带重叠部分尽可能的小，这样就可以在频域通过时，不需改变滤波方法而将信号和噪音分隔开来。但是，如果信号和噪音的频域重合时，用该方法进行噪音处理的效果就比较差。(digital image in the selection process will be subject to regular noise pollution. Therefore, the digital image should be carried out to deal with the noise. Based on the traditional Fourier Transform method of signal to noise, can result in a signal and noise bands overlap small as possible, so it can be adopted in the frequency domain, the need to change methods of filtering the signal and noise to separate. However, if the signal and noise in the frequency domain coincidence, the method for dealing with the effects of noise on the relatively poor.)

说明：  一个简单的matab的小波去噪程序，算法采用WT的方法，实现了较好的信号去噪效果(A simple matab wavelet denoising procedure, the algorithm using WT method to achieve a good signal de-noising effect)

说明：  提供坐标轴缩放、转换、设置的matlab环境模版。(Provide axes scaling, conversion, set the template of the matlab environment.)
