NEWTON-RAPHSON

说明：  这是用matlab编写的又来绘制KOCH曲线的源代码(This is again written in matlab source code for drawing curves KOCH)

Zigzag scanner of 2d matrix or images! it is usefull to convert the images or matrixes for comrepssion

彩色图像批量转换为灰度图像并自动保存，刚刚写好的一个小程序(Batch convert color images to grayscale images and automatically save, just a small program written)

说明：  这是基于吴和黄的的研究进而得到"percenta"的方法(This is used to obtain the "percenta" line based on Wu and Huang)

Computes fourier series

说明：  在matlab中产生心电信号的程序。很实用(ECG signals generated in the matlab program. Very practical)

说明：  This is a code for tsp transporter seller programming with matlab, enjoy!

Clustering an image using k-means algorithm

用BP进行非线性动态系统辨识 (BP carried out using nonlinear dynamic system identification)

该算法是经典的信噪比估计算法——误差矢量幅值法，通过计算接收信号中同相分量和正交分量的二、四阶矩，该算法能够很好的估计信号的信噪比(The algorithm is a classic signal to noise ratio estimation algorithm- the error vector magnitude method, by calculating the received signal with the phase component and quadrature component of the second, fourth-order moment, the algorithm can estimate a very good signal to noise ratio)
