用快速傅立葉轉換來求出訊號頻譜的練習過程，並舉一個實例:用FFT來算方形孔徑的遠場繞射(Exercises of the signal spectrum is obtained using a fast Fourier transform FFT to count the the square aperture far-field diffraction)

基于matlab开发的通用有限元软件的源程序部分，最新版本(Matlab-based general-purpose finite element software development source part, the latest version)

【实例简介】

图像的小波去噪,给灰度图像加上一定量的高斯噪声,再采用小波变换的方法去噪,计算去噪前后图像的PSNR。(Wavelet Denoising images to grayscale images coupled with a certain amount of Gaussian noise, and then using the method of wavelet transform denoising calculated before and after denoising images PSNR.)

svpwm模型，主要是对永磁电动机进行空间矢量的控制(svpwm model)

说明：  OFDM系统中基于LS 和 MMSE 的信道估计(OFDM Systems Based on LS and MMSE channel estimation)

对预处理及分割之后的图像进行识别 利用BP神经网络进行训练 学习(On after pretreatment and segmentation of image recognition using BP neural network for training study)
