说明：  求解系数矩阵由16阶Hilbert方程组构成的线性方程组， 3、共轭梯度法；(Solving the linear equations consisting of 16-order Hilbert equations of coefficient matrix. 3. Conjugate gradient method;)

简短的MATLAB语言，求出以V为水平初速度的物体下降弹道曲线方程及速度方程。以水平方向和竖直方向分解。(Short MATLAB, to find the initial velocity V as the level of objects down ballistic curve equation and rate equation. Horizontal and the vertical decomposition.)

5中不同目标函数的ICA方法，这是本人一个多月的心血，希望对大家有帮助。(5 different objective function ICA method, which is I am more than a month of hard work, we hope to help.)

分别在2幅灰度图像中加入一定量的高斯噪声和椒盐噪声，噪声强度自定。然后采用3×3的均值滤波器和3×3中值滤波器分别对噪声图像进行处理，给出两种处理方法的峰值信噪比(PSNR)；仿效“中值滤波”的方法，对原图像分别进行“极大值滤波”和“极小值滤波”，对所形成的图像给出说明。(Two gray-scale images a certain amount of Gaussian noise and salt and pepper noise , noise intensity since .)
