Matlab中二进制值的均匀分布

要使用{0,1}中的元素生成1个随机向量,请执行以下操作:

unidrnd(2,sizeOfVector,1)-1

其他的变种是相似的。

如果你想得到均匀分布的0和1,你想使用 randi rand

%# create a such that each row contains a vector

a = randi(1,N,sizeOfVector); %# for uniformly distributed 0's and 1's

%# if you want, say, 60% 1's and 40% 0's, use rand and threshold
a = rand(N,sizeOfVector) > 0.4; %# maybe you need to call double(a) if you don't want logical output

%# if you want a random number of 1's and 0's, use
a = rand(N,sizeOfVector) > rand(1);
