loop with easy underfunction

function tretti

for k=1:3
F=results(k)
end

function h=results(k)
A ={k*2};
A1(k)= A
h=A1

%output: F=[] [] [6]
%what i want: F=[2] [4] [6]         //cell array

Sorry, the question is: why is my underfunction not remembering my earlier value of A1 and how can i make it to remember?

Answer 1

Because you are overwriting it every iteration.

function F=tretti
for k=1:3
    F{k}=results(k);
end

function h=results(k)
A ={k*2};
A1(k)= A;
h=A1;

You should look into cellfun, it may be really useful for what you are trying to do.

yes but i dont have a cell array that i want to aply a function on. I want to make a cell array [2] [4] [6] [8] [10].... cellfun(func,A) my function is take k*2 but what is my A and how do i create it?

The modification of your code should work. You could also generate it as a vector or matrix, and then convert it to a cell with num2cell (or mat2cell).
