非常好的额matlab学习课件，是GUI的哦，哈哈，希望可以对你有帮助(Very good amount matlab learning courseware, the GUI Oh, ha ha, I hope you can help)

pn sequence generator

this is a MPSK mudulation with BER and PSD .

设r是f(x) = 0的根，选取x0作为r初始近似值，过点（x0,f(x0)）做曲线y = f(x)的切线L，L的方程为y = f(x0)+f (x0)(x-x0)，求出L与x轴交点的横坐标 x1 = x0-f(x0)/f (x0)，称x1为r的一次近似值。过点（x1,f(x1)）做曲线y = f(x)的切线，并求该切线与x轴交点的横坐标 x2 = x1-f(x1)/f (x1)，称x2为r的二次近似值。重复以上过程，得r的近似值序列，其中x(n+1)=x(n)－f(x(n))/f (x(n))，称为r的n+1次近似值(Let r is f (x) = 0 root, select the initial approximation x0 as the r, over point (x0, f (x0)) to do the curve y = f (x) the tangent L, L the equation y = f ( x0)+ f ' (x0) (x-x0), find the intersection of L and the x-axis of abscissa x1 = x0-f (x0)/f' (x0), x1 is called an approximation r. Through points (x1, f (x1)) to do the curve y = f (x) the tangent, and find the intersection of the tangent with the x-axis of abscissa x2 = x1-f (x1)/f ' (x1), x2 is called r the second approximation. Repeat the process, get an approximation of the sequence r, where x (n+1) = x (n)-f (x (n))/f ' (x (n)), as an approximation of r n+1 times)

说明：  matlab代码功能实现图像的距离变化，已经通过调试成功！(matlab code image of the distance function changes have been adopted successfully debug!)

this algorithm simulates natural behavior of weeds in colonizing and finding suitable place for reproduction.IWO differs from other evolutionary algorithms in the way of reproduction,spatial dispersal and competitive exclusion
