MATLAB: Insert zeros in a vector

Question

Let's assume my vector is

A = [1 2 3 7 9 10 45 93 122 150]';

I want to put zeros in between these numbers.

A = [1 2 3 0 0 0 7 0 9 10 0 0 …..]';

Answer 1

One of ways:

A = [1 2 3 7 9 10 45 93 122 150]'
ii = randi(3,numel(A),1);
t = cumsum(ii) < numel(A);
ii = ii(t);
z = arrayfun(@(x)zeros(x,1),ii(1:end-1),'un',0);
C = mat2cell(A(1:sum(ii)),ii,1);
out = [C';[z',{[]}]];
out = cat(1,out{:});
