matlab实用程序源代码，第一部分，包括很多基础源代码(matlab)

说明：  出一种新 的SVPWM 算法。采用SPWM 中调制波与载波相比较的规则采样思路，通过在静止坐标系下直接 计算每个参考电压矢量所对应的三相调制波的函数值，进而得到每相电压在一个PWM 周期中的占空比。(A new SVPWM algorithm. SPWM modulation used in the carrier wave, compared with the rules of sampling ideas, through the static coordinate system directly calculated for each reference voltage corresponding to the three-phase vector modulation wave function, which has been in a phase voltage of each PWM cycle accounting air ratio.)

说明：  matlab里面使用三倍中误差法消除观测粗差，去除噪声。(matlab error method which uses three times in the elimination of Gross Errors, remove noise.)

利用matlab求QAM的一个程序实例，很实用(To seek QAM by matlab)

小波神经网络是一种利用小波分析和人工神经网络结合的智能模型，是一种人工智能模型。本程序利用小波神经网络进行短时交通流量预测。(Wavelet neural network (WNN) which is the combination of wavelet analysis and artificial neural network is used to predict the future traffic.)

RGB和Lab颜色空间互相转换Matlab代码，亲测，非常好(Codes to transfer between RGB and Lab color space. Perform perfectly)

这是一个关于HHT变换的matlab源码，把它复制进去matlab就可以直接使用。很实用。(This is a transformation on the HHT matlab source code, copy it into matlab can be used directly.)

SALSA的MATLAB相关编码和源程序(SALSA in the MATLAB source code and related)

signal processing: downsampling/upsampling a signal and using of ZOH.

可以用Matlab画坐标系，使用比较方便。(Coordinate system using Matlab painting, more convenient to use.)
