Access cell array using an indexed array

Hi,

I have a short question.

Suppose that I save some data into a cell array like this,

 T{1,1} = [1,2,3];
 T{2,1} = [4,5,6];
 T{3,1} = [7,8,9];

and I have an index array like this.

 idx = [3,2,1];

In this situation, I want to get the result like this.

 ans = [3,5,7]

How can I make a code??

Really thanks in advance.

Hi Changho,

You can refer to the following code snippet to get the desired output.

function out=my_func(T,idx)
out=[];
for i=1:size(T)
    temp=T{i};
    out=[out temp(idx(i))];
end
end

Hope this helps you.
