这个Matlab程序实现最速下降算法。最速下降法是一种最基本的算法，它在最优化方法中占有重要地位.最速下降法的优点是工作量小，存储变量较少,初始点要求不高；缺点是收敛慢，最速下降法适用于寻优过程的前期迭代或作为间插步骤，当接近极值点时，宜选用别种收敛快的算法. (Matlab implementation of this procedure steepest descent algorithm.)

用于实现森林防火隔离带的计算和画图 我用MATLAB编的程序，存为txt文档格式，方便大家查看。这是我们组在学校国际赛选拔赛时编的程序，用于实现森林防火隔离带计算和画图。可立即执行。(Forest Fire Barrier used to implement the calculation and drawing program I use MATLAB code, save it as txt file format to enable easy viewing. This is our group in the school when the series of international competitions qualifying procedures for the realization of Forest Fire Barrier calculation and graphics. Can be implemented immediately.)
