Question

【Matlab】怎样随机产生几个数，且这几个数满足一定的条件？具体描述见下：

使用matlab怎样随机产生5个数，且满足一下条件：

a+b+c+d+e=69
1=<a<=30
1=<b<=30
1=<c<=30
1=<d<=24
1=<e<=24
哪位可以帮忙实现一下。谢谢

Answer 1

T = 69;
Min1 = 1;
Min2 = 1;
Max1 = 31;
Max2 = 24;

DE = randi([Min2 Max2],2,1);

while 1
LeftOver = T - sum(DE);
ABC = [];
for i = 1:2
ABC = [ABC;randi([Min1 ((LeftOver-1)>Max1)*Max1+(LeftOver-1<=Max1)*(LeftOver-1)],1)];
LeftOver = LeftOver - ABC(end);
end
if LeftOver <= Max1 % 防止最后一个随机数过大
break;
end
end

ABC = [ABC; LeftOver];
Result = [ABC;DE];

Answer 2

clear;clc

while 1
A=[unifrnd(1,30,1,3),unifrnd(1,24)];
e=69-sum(A);
if(1<=e && e<=24)
A=[A,e]
break;
end
end

追问

忘说了，这5个数是个整数，怎么弄。等会分全给你

追答

clear;clc

while 1
A=[randint(1,3,[1,30]),randint(1,1,[1,24])];
e=69-sum(A);
if(1<=e && e<=24)
A=[A,e]
break;
end
end
