function write numberous vectors out

Hellow, i want to write a function that generates a amount of vectors (projections) with length size. I have written this but it doesnt work. Plz help

    function f(i) = opvullen( projections,Lx,Ly )
  %try to write vectors
  size=Lx*Ly;
  for i=1:projections
      f(i)=zeros(1,size);
  end

How does it not work? Are you getting an error message?

As cell array:

function f = opvullen( projections,Lx,Ly )
%try to write vectors
size=Lx*Ly;
f = cell(projections,1);
for i=1:projections
    f{i}=zeros(1,size);
end

Or, as numeric array since they are all the same size

function f = opvullen( projections,Lx,Ly )
%try to write vectors
size=Lx*Ly;
f = zeros(size,projections);
for i=1:projections
    f(:,projections)=zeros(1,size);
end
