wuyufei的turbo程序，做turbo的人一定要看的matlab程序。(wuyufei the turbo procedure, turbo make sure to look at the matlab program.)

this code about optimization

算法优化非常好，几乎没有循环，可以广泛的应用于数据预测及数据分析,利用最小二乘法进行拟合多元非线性方程。( Algorithm optimization is very good, almost no circulation, Can be widely used in data analysis and forecast data, Multivariate least squares fitting method of nonlinear equations.)

佛洛伊德方法用二值模型来形成多灰度图像的真实效果，希望分享(Digital halftoning is the process of converting a continuous-tone images into strictly black and white images such that, when viewed by the human visual system, the pattern creates an illusion of being a continuous shade of gray. )
