Delete zeros from an array using for loops

Hi I need delete zero elements of an array.

Note: I know theres a lot of way to complete this task.

Example: A = [1,0,2,3,0,0];

B = B(B~=0);

or

B = nonzeros(A);

I'm tryng this:

% Know the number of zeros

LA = length(A); Cont = 0;

for i = 1: LA

 if A(i) == 0

 Cont = Cont + 1;

 end

end

% Dimention of the array B

LB = LA-Cont; B = zeros(LB,1);

for j=1:LB for k=1:LA

if A(k) ~= 0

    B(j) =[A(k)];

end
end
end

Using this code I get this:

B = [3,3,3];

Because this code not reset when find a number different of zero.

Any idea? (using for loops)

A = [1,0,2,3,0,0];
B=[];
for k=1:length(A)
  if A(k)~=0
    B=[B,A(k)];
  end
end
