Welch法：Welch法對(duì)Bartlett法進(jìn)行了兩方面的修正：一是選擇適當(dāng)?shù)拇昂瘮?shù)w(n)，并在周期圖計(jì)算前直接加進(jìn)去，加窗的優(yōu)點(diǎn)是無(wú)論什么樣的窗函數(shù)均可使譜估計(jì)非負(fù)。二是在分段時(shí),可使各段之間有重疊，這樣會(huì)使方差減小。

設(shè)有一個(gè)背包可以放入的物品重量最重為s，現(xiàn)有n件物品，它們的重量分別為w[0]、 w[1]、w[2]、…、w[n-1]。問能否從這n件物品中選擇若干件放入此背包中，使得放入的重量之和正好為s。如果存在一種符合上述要求的選擇，則稱此背包問題有解（或稱其解為真）；否則稱此背包問題無(wú)解（或稱其解為假）。試用遞歸方法設(shè)計(jì)求解背包問題的算法。

The Window Design Method The basic idea behind the design of linear-phase FIR filters using the window method is to choose a proper ideal frequency-selective filter [which always has a noncausal, infinite duration impulse response] and then truncate its impulse response hd[n] to obtain a linear-phase and causal FIR filter h[n]. To truncate the impulse response of the ideal filter a time window w[n] is used. Available windows in Matlab are rectangular [or boxcar in Matlab], bartlett, hamming, hanning

The code performs a number (ITERS) of iterations of the Bailey s 6-step FFT algorithm (following the ideas in the CMU Task parallel suite). 1.- Generates an input signal vector (dgen) with size n=n1xn2 stored in row major order In this code the size of the input signal is NN=NxN (n=NN, n1=n2=N) 2.- Transpose (tpose) A to have it stored in column major order 3.- Perform independent FFTs on the rows (cffts) 4.- Scale each element of the resulting array by a factor of w[n]**(p*q) 5.- Transpose (tpose) to prepair it for the next step 6.- Perform independent FFTs on the rows (cffts) 7.- Transpose the resulting matrix The code requires nested Parallelism.

代入法的啟發(fā)示搜索 我的代碼實(shí)現(xiàn)是：按照自然語(yǔ)言各字母出現(xiàn)頻率的大小從高到低（已經(jīng)有人作國(guó)統(tǒng)計(jì)分析了）先生成一張字母出現(xiàn)頻率統(tǒng)計(jì)表（A）--------(e),(t,a,o,i,n,s,h,r),(d,l),(c,u,m,w,f,g,y,p,b),(v,k,j,x,q,z) ，再對(duì)密文字母計(jì)算頻率，并按頻率從高到低生成一張輸入密文字母的統(tǒng)計(jì)表（B），通過兩張表的對(duì)應(yīng)關(guān)系，不斷用A中的字母去替換B中的字母，搜索不成功時(shí)就回退，在這里回朔是一個(gè)關(guān)鍵。
