使用矩形窗函数，分析信号截短对离散傅立叶变换的影响，其中原始信号为正弦函数(Use a rectangular window function, the analysis of the signal truncated discrete Fourier transform, which the original signal is a sine function)

用最速下降法求解多维函数的极值 function [x,minf]=minFD(f,x0,var,eps) 目标函数：f 初始点：x0 自变量向量：var 精度：eps 目标函数取最小值时的自变量值：x 目标函数的最小值：minf( With the steepest descent method for solving the multi-dimensional function of the extreme value function [x, minf] = minFD (f, x0, var, eps) target function: f Initial Point: x0 argument vector: var Accuracy: eps target function takes the minimum value of the independent variable values: x minimum target function: minf)
