利用matlab求解时滞微分方程。常微分方程（ODE）和延迟微分方程（DDE）被用来描述许多有趣的现象。 虽然ODE包含依赖于自变量（“时间”）的当前值的解决方案的衍生物，但DDE还包含衍生物，其依赖于前一时间的解决方案。 在整个科学模型中出现了DDE [1]。 尽管ODE和DDE之间存在明显的相似性，但DDE问题的解决方案可能与ODE问题的解决方案在几个引人注目的重要方面存在差异[2] [20]。 这部分是因为缺乏用于解决DDE的通用软件。(Solving Delay Differential Equations with dde32)

对图像进行逐点计算，并且取最大值和最小值的差值作为该点新的灰度值。 在区别边缘点和非边缘点时，首先确定一个阈值T，若图像中像素点的新 值大于该门限值，则可以初步确定为边缘点，小于T的新值被判断为非边缘点.(Image point by point basis, and taking the maximum and minimum points of difference as the new gray value. Edge in the difference between point and non-edge point, first determine a threshold T, if the image of the new pixel value is greater than the threshold, you can initially identified as the edge point, the new value is less than T have been judged as non-edge point.)
