How to extend/add elements to an array?

I want to extend an array at the points were the array are 0.

For example an array like this:

A=[2 3 4 5 0 1 4 5 5 0 3 4 0 2 0 ];

At each zero in A i want to extend by B=[3 2 3 5];

so the new array will be:

C=[2 3 4 5 0 0 0 1 4 5 5 0 0 3 4 0 0 0 2 0 0 0 0 0];

Answer 1

A = [2 3 4 5 0 1 4 5 5 0 3 4 0 2 0 ];
B = [3 2 3 5];

out = A(sort([find(A),repelem(find(A == 0),B)]));

@Andrei

I wrote wrong in the first place, i want all the zeros to exceed so B will be for example:

B= [3 2 3 5];

out will then be =[2 3 4 5 0 0 0 1 4 5 5 0 0 3 4 0 0 0 2 0 0 0 0 0];

Brilliant! Thanks!

Answer 2

[Rikke]

I got the solution for B= [3 2 3 5]. Thanks Andrei!

A=[2 3 4 5 0 1 4 5 5 0 3 4 0 2 0 ];
B=[3 2 3 5];
jj = find(A == 0);
out = A(sort([find(A),jj,repelem(jj,B)]));

Madhan I think ii is if you want to add zeros to spesific zeros in the array and not all of them.

Yes ;)
