MATLAB: Choose row cell of matrix

Question

I have

 A=[1 2 0.1 0.2;...
    1 5 0.2 0.2;...
    2 3 0.4 0.4;...
    2 4 0.9 0.8;...
    2 5 0.3 0.4;...
    3 4 1.1 2.2]

and

B={[1,2,5],[3,4,6]} 

I want to get a C that rows of it, is B and column of it is all column of A

C=cell(1, size(B,2));
for i=1:length(B)
    for j=1:length(B{i})
    C{i}(j)=A(j,:)
    end
end

I want this result

C={[1 2 0.1 0.2 ;...
    1 5 0.2 0.2 ;...
    2 5 0.3 0.4],...
   [2 3 0.4 0.4 ;...
    2 4 0.9 0.8 ;...
    3 4 1.1 2.2]}        

Answer 1

A general solution in one line:

C = cellfun(@(r)A(r,:),B,'uni',0)
