matlab code regarding annealing and computing

先定义允许状态S={(x,y)|x=0或3,y=0,1,2,3 x=y=1,2}, 允许决策D={(u,v)|u+v=1,2},求dk<-D(k=0,1,2,…,n),使 状态Sk<-S按照状态转移律S(k+1)=S(k)+(-1)^k*dk,由初始状态 S1=[3,3]经有限步到达状态S(n+1)=[0,0].此为求解多步决策问题( First define to allow the state S = ((x, y) | x = 0 or 3, y = 0,1,2,3 x = y = 1,2), to allow the decision-making D = ((u, v) | u+ v = 1,2), seek dk < -D (k = 0,1,2, ..., n), so that state Sk < -S state transition in accordance with law S (k+1) = S (k )+ (-1) ^ k* dk, from the initial state S1 = [3,3] by the finite-step to reach the status S (n+1) = [0,0]. This is a multi-step decision-making problem solving)

Matlab Code to suppress estimate PSD, Noise in speech and minimise it and thus improve SNR

水声有关近场信源定位的matlab程序，具有较高的参考价值！(The near-field acoustic source location matlab program, with a high reference value!)

自己写的costas信号程序，需要的可以下载(I wrote it myself costas. A friend in need can be downloaded.)

可以对已有的信号求其循环谱，信号可以通用的。(The cyclic spectrum of the existing signal can be obtained, and the signal can be universal.)
