Hi guys
I have two cell arrays A, B.
A = {[1 -1 1], [2 3 6 5]};
B = {[2 1], [1 4]};
B is the index for A.
I'd like to have a certain function A(B) give me
C = {[-1 1], [2 5]}.
Aside from cellfun, Is there any other ways to do this?
Thanks,

what do you mean B is the index of A? and how C is related to A and B

C{i} = A{i}(B{i})

c = cellfun(@(a,b) a(b),A,B,'UniformOutput',false)
or
c = arrayfun(@(x)A{x}(B{x}),1:length(A),'UniformOutput',false)

Added a solution with arrayfun, but I don't know if arrayfun is ok
