SVM-Classification-2D-examples

1）已知2N点实数序列 N=64。用一个64点的复数FFT程序，一次算出 ，并绘出频谱 。 （2）已知某序列 在单位圆上的N=64等分样点的Z变换 。用N点IFFT程序计算 ，绘出图像 。 (1) known 2N-point sequence of real numbers N = 64. With a 64-point complex FFT process, a calculated and mapped the spectrum. (2) known to a certain sequence in the unit circle on the N = 64 sub-samples of the Z transform. N-point IFFT procedures used, the mapped image.)

小波变换的matlab代码，用于信号处理(Wavelet transform matlab code for signal processing)

利用matlab进行五点三次法平滑处理(时域和频域)(Using matlab 5.3 times France smoothing process (time domain and frequency domain))

Genetic Algoritthm MATLAB Code for Quadratic Assignment Problem(QAP)

SparseArrays map integers to Objects. Unlike a normal array of Objects, there can be gaps in the indices. It is intended to be more efficient than using a HashMap to map Integers to Objects.

说明：  函数求导函数文件定义以及无线通信技术相关实现(function define of derivative)

说明：  FFT高通处理图像和DCT高通处理图像，能够通过这两个程序的对比，来了解这两种处理方式的异同之处。(FFT DCT Qualcomm Qualcomm processing images and image processing, be able to compare the two programs, to understand both the similarities and differences between treatments.)

i guess this is the last time
