说明：  这是光学衍射部分的内容，，衍射部分的基本上都包括了，(This is part of the contents of the optical diffraction, the diffraction part basically includes,)

matlab实现彩色图像的余弦压缩变换，分阈值不同显示(matlab color image compression cosine transform, threshold different display)

说明：  在matlab2019B中，已经将princomp函数改为了pca函数，功能相同，函数名改变，所以如果要使用，记得将老版本的代码中的princomp改为pca。(In MATLAB 2019b, the principal function has been changed to PCA function. The functions are the same, and the function name changes. So if you want to use it, remember to change the principal function in the old version of the code to PCA.)

中心显示格式和修正中心显示格式求解poisson方程，矩形区域，狄利克雷边界情况！(Center display format and the correction center display format for solving poisson equations, rectangular area, Dirichlet boundary conditions!)

Dynamic Time Wrapping

小波分析是目前数学中一个迅速发展的新领网域，它同时具有理论深刻和应用十分广泛的双重意义。信号处理的目的就是：准确的分析、诊断、编码压缩和量化、快速传递或存储、精确地重构（或恢复）。(Wavelet analysis is a rapidly developing new collar domain in mathematics, which has both theoretical significance and profound and extensive application. The purpose of signal processing is: accurate rapid analysis, diagnosis, coding and quantization, transmission or storage, accurate reconstruction (or recovery).)
