压缩感知（compressed sensing，cs）在MRI上的应用，该程序生成傅里叶变换域的射线采样模式用作随机测量 (Compressed sensing (compressed sensing, cs) on MRI, the program generates the rays of the Fourier transform domain sampling mode as random measurement)

说明：  用matlab符号对象求解非线性方程组，进行函数绘图(solve nolinear equations used matlab)

matlab相关教程，希望能给大家提供帮助，可以看看的资料(matlab tutorial, I hope to give help, you can see the information)

一个二维静电场，电位函数为φ（x, y），将正方形分成25个正方形网格。有16个内部网格点。假定16个网格点的初值都定为零，试用超松弛法确定16个内部网格点的电位值。(A two dimensional electrostatic field, the potential function for phi (x, y), the square into 25 square grid. There are 16 internal grid point. Assume that 16 mesh point of initial value at zero, trial overrelaxation method to determine the potential value of 16 internal grid point.)
