OFDM程序，這么安排矩陣的目的是為了構(gòu)造共軛對(duì)稱矩陣 共軛對(duì)稱矩陣的特點(diǎn)是 在ifft/fft的矢量上 N點(diǎn)的矢量 在0，N/2點(diǎn)必須是實(shí)數(shù) 一般選為0 1至N/2點(diǎn) 與 （N/2）+1至N-1點(diǎn)關(guān)于N/2共軛對(duì)稱

任務(wù)：一堆猴子都有編號(hào)，編號(hào)是1，2，3 ...m ,這群猴子（m個(gè)）按照1-m的順序圍坐一圈，從第1開始數(shù)，每數(shù)到第N個(gè)，該猴子就要離開此圈，這樣依次下來，直到圈中只剩下最后一只猴子，則該猴子為大王。 功能：輸入數(shù)據(jù)：輸入m，n（m，n 為整數(shù)且n<m） 輸出形式：中文提示按照m個(gè)猴子，數(shù)n 個(gè)數(shù)的方法，輸出為大王的猴子是幾號(hào) ，建立一個(gè)函數(shù)來實(shí)現(xiàn)此功能
