MATLAB神经网络工具箱的介绍 是一篇很好的论文 介绍的很详细 (MATLAB neural network toolbox is a good introduction to the papers described in great detail)

tasks assigned in matlab

1.产生阶数为n的m序列。 2.测试阶数为n的m序列是否满足m序列性质。（与相应的m序列生成程序配合使用。实现检测效果）(1. Generate the order number n, m sequence. 2. Testing the order of n-m-sequence satisfies the nature of m sequences. (With the corresponding m-sequence generation program used in conjunction. To achieve detection results))

也是利用最小二乘法对椭圆进行数据拟合，不过考虑到图像大小问题，这里只选取100个边缘点，点的个数也可以自行设置。(Ellipse is the least square method of data fitting, but taking into account the size of the image, here select only edge points 100, the number of points you can set your own.)
