MATLAB: Buildind special vector? V(3)=V(6)=V(9)…=0

vectorvectorizationvectors

How can I build

V=[1 1 0 1 1 0 1 1 0 1 1 0….]vector.I want to put N value and it will reply me V vector..

Elements fo V will be V(3)=V(6)=V(9)…=0

Another guess:

V = ones(1, N);
V(3:3:end) = 0;

Do not use "input" as name of a variable, because it is a name of a built-in function.

in  = [2, 2, 5, 6, 6, 6, 1, 1, 1, 1, 4, 3, 3];
out = cumsum([1, diff(a) ~= 0]);
>> out = [1 1, 2, 3, 3, 3, 4, 4, 4, 4, 5, 6, 6]

full( ind2vec(V+1).' )

or,

accumarray((1:length(V)).', V+1)

maxV = max(V);
LV = length(V);
M = zeros(LV, maxV+1);
M(V * LV + (1:LV).') = 1;

 maxV = max(V);
 LV = length(V);
 M = zeros(LV, maxV+1);
 M( sub2ind(size(M), (1:LV).', V+1) ) = 1;
