How to keep values whose corresponding index is present?

Hi all

     array1 = {1,1,1,0.92,0.61,0.47,0,0;1.6,1,1,1,0.6,0.5,0.4,0.8};
     array2 = {[3,4,5,6];[4,5,7,8]};

I need to keep only those values in array 1 whose corresponding index value is present in array2. e.g. Result may look like this:

    ResultantArray = {[1,0.92,0.61,0.47];[1,0.6,0.4,0.8]}

Thanks in advance.

ResultantArray = arrayfun(@(Row) cell2mat(array1(Row,array2{Row})), (1:size(array1,1)).', 'uniform', 0)

Try this:

array1 = {1,1,1,0.92,0.61,0.47,0,0;1.6,1,1,1,0.6,0.5,0.4,0.8};
array2 = {[3,4,5,6];[4,5,7,8]};

ResultantArray = cellfun(@(idx) array1(:,idx), array2, 'Uni',0);
ResultantArray{1}(1,:)
ResultantArray{2}(2,:)

ans =

    1×4 cell array

      {[1]}    {[0.9200]}    {[0.6100]}    {[0.4700]}

ans =

    1×4 cell array

      {[1]}    {[0.6000]}    {[0.4000]}    {[0.8000]}
