CLOCK
钟面上的时针和分针之间的夹角总是在 0 ~180之间 ( 包括 0 和180 ) 。举例来说,在十二点的时候两针之间的夹角为 0 ,而在六点的时候夹角为180 ,在三点的时候为90 。本题要解决的是计算 12:00 到 11:59 之间任意一个时间的夹角。(The angle between the hour and minute hands of the clock face is always between 0 to 180 (including 0 and 180). For example, twelve o' clock, when the angle between the two pin 0, in the six o' clock when the angle is 180, three points for 90. This question must be resolved are the angle of the calculation of 12:00 to 11:59 any one time.)

pso
粒子群优化(Particle Swarm Optimization - PSO) 算法是一种新兴的有潜力的进化算法( Evolutionary Algorithm - EA) .PSO 算法,和遗传算法相似,它也是从随机解出发,通过迭代寻找最优解,它也是通过适应度来评价解的品质. 但是它比遗传算法规则更为简单,它没有遗传算法的“交叉”(Crossover) 和“变异”(Mutation) 操作. 它通过追随当前搜索到的最优值来寻找全局最优。-pso

09-MIMO系统容量仿真程序
说明: function C=capacity(SNR,Nt,Nr)
%SNR=0; %定义信噪比为0HZ
A=10^(SNR/10); %信噪比的单位转换关系式
Im=eye(min(Nr,Nt)); %这里的"1"为发射天线和接收天线两者数目少的根数
sum=0; %初始化sum为0
for i=1:10000 %程序循环10000次
H=randn(Nr,Nt); %产生高斯信号源
if Nr<Nt
Q=H*H'; %求威沙特矩阵
else
Q=H'*H;
end
sum=sum+log2(det(Im+A*Q/Nt)); %10000次循环得到的信道容量总和
end
C=sum/10000 %10000次循环的平均值(function C=capacity(SNR,Nt,Nr)
%SNR = 0;% defines SNR as 0Hz
A = 10 ^ (SNR / 10);% s / N unit conversion relation
Im = eye (min (NR, NT));% here "1" is the number of the less number of transmitting antenna and receiving antenna
Sum = 0;% initialize sum to 0
For I = 1:10000% program cycles 10000 times
H = randn (NR, NT);% produces Gaussian signal source
if Nr<Nt
Q = h * H ';% to find the weissard matrix
else
Q=H'*H;
End
Sum = sum + log2 (DET (IM + A * q / NT));% sum of channel capacity from 10000 cycles
End
C = sum / 10000% average of 10000 cycles)
