MATLAB: 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].

matrix array

for example

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

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

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

Hi bus14,

Try this:

m=zeros(804,200);
m([1,2,4],:)=1;
m2=reshape(m,800,[]);
m2(:,201)=[];

MATLAB: I have a matrix [1 1 1 0; 0 1 1 0;1 1 0 1; 0 0 1 1]

A =  [1 1 1 0; 0 1 1 0;1 1 0 1; 0 0 1 1];
B = reshape(A(1:end-1),3,5);
B
B =
     1     0     1     1     0
     0     1     0     0     0
     1     1     1     1     1

To get it as 5x3 is just changing the call to reshape. You need to make sure you know in which order you want the elements to be reshaped. Remember that MATLAB stores the elements of an array going down the columns.
