create a vector of 0 and 1s that takes 1 at a fixed interval

I would like to create a vector of 0s that takes 1 at a given (m) interval. For example, if m=2, the vector will be like

0,0,1,0,0,1,0,0,1,...

what will be a simpler way to create such vector?

Answer 1

[Fangjun Jiang]

m=2;
N=100;
a=zeros(1,N);
a(m+1:m+1:N)=1

most intuitive.

repmat([zeros(1,m), 1],1,5)

Thank you.

Hi,

O=zeros(1, 20);
m=input('m = ');
IN=m+1:m+1:numel(O);
O(IN)=1;
