根据国标编写的数控机床轴线定位精度和重复定位精度计算程序( a matlab source code to calculate positioning accuracy and re-orientation accuracy )

此程序的重点在于用算法完成了OFDM自适应功率分配，做自适应的学友可以参考啊(The focus of this program was completed by algorithm adaptive OFDM power distribution, make adaptive Xueyou can refer to ah)

用矩阵撕裂法，多次用matlab运算，得出复杂系统的15个节点的电压(Tear voltage matrix method, repeatedly using matlab computing, complex systems derived 15 nodes)

这是2009年huang在EMD基础上改进的算法EEMD的matlab代码！(This is the huang in 2009 based on the improved EMD algorithm EEMD matlab code!)

傅里叶变换和小波变换重建图像的比较效果，这个程序可以用来实现四个要求：1、FFT和WT重建效果比较；2、通过改变小波来比较重建效果；3、通过改变分解层数来比较重建效果；4、通过改变大系数个数来比较重建效果。其中还有一个计算PSNR的程序(the comparative effect of reconstruction image by Fourier transform and wavelet transform 。 the program can be used to achieve the four requirements: 1, FFT, and WT reconstruction effect 2, by changing the wavelet to compare the reconstruction effect 3, by changing the decomposition layers to compare the reconstruction effect 4, by changing the number of large coefficient of comparative reconstruction results. Including a procedure of calculating PSNR )
