说明：  黄金分割法matlab程序，输入最优化目标函数，区间，精度，得到整个过程的黄金分割过程表与最优解，最优值，不止最终结果，每一步变换都有给出，完全没有错，很详细，有运行结果说明。
(Golden section method matlab program, input the optimization objective function, interval, precision, get the golden section process table and the optimal solution of the whole process, the optimal value, not only the final result, each step of transformation has been given, there is no error, it is very detailed, there is a description of the operation results.)
