spectrogram_fft

实序列FFT快速算法，用N点FFT计算2N点实序列的FFT，比直接进行2N点FFT运算减少一半运算量。(Real sequence FFT fast algorithm, using N-point FFT calculation 2N point real sequence of FFT, than the direct 2N-point FFT computation halved.)

MATLAB CODE FOR IMAGE ARITHMATIC

图像金字塔采样，可以根据一副图像得到不同分辨率的子图。利用高斯窗等，可以很好的保留全局显著信息，主要用于压缩图像等。

ecg signal generation using fourier series

pARTIAL TRANSMIT SEQUENCE is very effective technique for papr reduction in OFDM.It divide OFDM sequence into several disjoint sub sequences and convert to time domain then Combine with complex phase factors to reduce PAPR.In this code matlab simulation of this technique is implemented

This is very simple code for neural network fitting in Matlab and comparing with linear regression.

同步压缩小波工具包，小波的一种改进，想在小波算法改进上造文章的可以试一试，可能会有不同的发现，直接解压放到matlab工具包即可使用，具体调用可以查看文件中的具体函数定义。
