How to avoid using for loops when declaring functions in a cell array

In my source codes:

clear all
fout=cell(1,10);
B=zeros(10,20);
for ii=1:1:10 
   fout{ii}=@(x) 2*pi*x*(1:1:20)+ii;
end
 
for ii=1:1:10
    B(ii,:)=fout{ii}(2);
end
 
display(B);

How can I use the matlab vectorization to declare functions in a cell array as well as to provide function outputs in one go rather than using two for loops? M

You only need 1 anonymous function if you include ii as a second input. ii must be a column vector and x must be a row vector.

fout = @(x,ii) 2*pi*x*(1:1:20)+ii;
B = fout(2,(1:10)'); 

Alternatively, the 2nd loop in your question can be replaced by

y = cell2mat(arrayfun(@(i){fout{i}(2)},1:10)');

however, your loop is more efficient, faster, and easier to read.

Thank you for your reply. I simplfied my original questions a lot. I wondered how to use arrayfun to replace the second for loop.
