run length encoding in matlab

it is a file to watermark the image file in matlab

数字滤波仿真程序，供大家参考！希望对大家学习有用！(digital filter simulation program, for your reference! We hope to learn useful!)

Creates a package named XPLAN as a wrapper over DBMS_XPLAN

一阶预测器的设计,可以查看权重系数图和均方误差图。(Predictor of first-order design, weight coefficient can view maps and mean square error map.)

说明：  进行多目标优化，主要是使用了NSGA-2的算法，在代码中进行了必要的标注(In the process of multi-objective optimization, nsga-2 algorithm is mainly used and necessary annotation is made in the code)

非常好的K近邻算法，算法进行了优化，速度也较快(very good！)

这是一个决策树的matlab实现，已经测试通过(This is a matlab implementation of decision tree, have the test pass)

高斯脉冲波源下的磁偶极子场的计算，并与fdtd法进行了比较(The analytical solution to the Hertzian Dipole (with a Gaussian pulse source) problem for comparison with the FDTD simulation.)

实现图像的DCT高通、低通滤波器并与傅里叶变换做比较.有图可见，经DCT低通滤波后，图像变得很模糊。因为DCT是FFT取其实部，能量减少，因此图像变得很模糊，没有经FFT滤波后的效果好。 经DCT高通滤波后的图像： 经DCT高通滤波后，图像的低频部分被滤除掉，图像变黑，只有边缘的痕迹可见。 (The DCT of image high-pass, low pass filter and compared with the Fourier transform.)
