MATLAB: How can i randomly insert 14 1’s in a array of two thousand zeros

arrayrandomrandom number generator

i.e. I have a array of two thousand zeros, in this I want to randomly insert 1, fourteen times. How can I do this?

A = zeros(1,2000);
A(randperm(2000,14)) = 1;

If you want to add a dark edge (that's what the zeros will be), at the bottom and to the right:

load mandrill
[m n] = size(X); %in your case it will be [1023 1023]

X = [ [X;zeros(1,n)] zeros(m+1,1)];

At the top and to the left:

load mandrill
[m n] = size(X); %in your case it will be [1023 1023]
X = [ zeros(m+1,1) [zeros(1,n);X] ];

Plus the two other alternatives, with the same principle:

 X = [[zeros(1,n);X] zeros(m+1,1)];
 X = [ zeros(m,1) [X;zeros(1,n+1)] ];

a = [1 2 3 4 5]
b = zeros(4,numel(a))
result = reshape([a; b],1,[])
