MATLAB: Function write numberous vectors out

vector

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

Best Answer

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
