ASK_FSK_PSK

skin segmentation base on RGB color space. does not work for gray level images

本代码为割线法求解非线性方程组。其调用格式为[r,m]=mulGXF1(F,x0,x1,eps) 其中，F:非线性方程组；x0初始解；x1：初始解；eps：解的精度；m：迭代步数。(The code for the secant method for solving nonlinear equations. Its call format [r, m] = mulGXF1 (F, x0, x1, eps) where, F: non-linear equations x0 initial solution x1: initial solution eps: solution accuracy m: the number of iterative steps.)
