Can anyone help me to generate a matrix of 0's and 1's randomly in which each contains only one 1 like [ 0 1 0 0 0; 1 0 0 0 0; 0 0 0 1 0].

for example

[0 1 0 0 0; 1 0 0 0 0; 0 0 0 1 0]

Answer 1

[Andrei Bobrov]

[~,ii] = sort(rand(3,5),2)
out = ii == 1

or

out = zeros(3,5)
[m,n] = size(out);
out(sub2ind([m,n],1:m,randperm(n,m))) = 1

+1 very neat.

@Andrei: your first solution producing sometime repeated values..like..

out =

     1     0     0     0     0
     1     0     0     0     0
     0     0     1     0     0

and in second solution, what is m and n ?

[Andrei Bobrov]

correction in the second solution

One 1 in each ... what? rows, columns, or both?

Given your examples and comment I assume both, so here is a simple one-liner. NR and NC are the number of rows and columns, respectively. Note that NC should be larger or equal to NR

A = full(sparse(1:NR, randperm(NC,NR), 1, NR, NC))
