各位大神，小弟一直在追一女孩，女孩是学计算机的，前天求我一问题，如下：
 已知一离散数组，数组中数的出现概率为p(xi=ai)=b,用matlab实现，产生一系列的随机数。
 本人没学过matlab ,看了两天，没啥效果，故求各位大神解答，望成全小弟~~~~感激不尽~~~~~~~

可尝试根据已知数据确定随机数的分布类型，然后确定相应的算法。

% This function is used for random number generation

X = [1 2 3 4 5];   %Number to use
P = [0.1 0.3 0.3 0.1 0.2 ]; % possibility to use

M = 10000; %how many numbers we want to generate

Temp = rand(1,M);

%Assign the possibility with length of intervals
% X1 - [0,0.1)
% X2 - [0.1,0.4)
% X3 - [0.4,0.7)
% X4 - [0.7,0.8)
% X5 - [0.8,1]

Index1 = find(Temp>=0   & Temp <0.1);
Index2 = find(Temp>=0.1 & Temp <0.4);
Index3 = find(Temp>=0.4 & Temp <0.7);
Index4 = find(Temp>=0.7 & Temp <0.8);
Index5 = find(Temp>=0.8 & Temp <=1);

Temp(Index1) = X(1);
Temp(Index2) = X(2);
Temp(Index3) = X(3);
Temp(Index4) = X(4);
Temp(Index5) = X(5);

Result = Temp
