matlab - Indexing Cell arrays for more efficient performance -

i have following code display 9-by-3 cell array:

data = cell (9,3);  col1 = [2, 3, 5, 7, 8, 11, 12, 15, 16];  col2 = {[1 1], [1 5], [3 9], [4 2], [4 6], [6 2], [7 6], [6 9], [9 9]};  col3 = {[2 3 4 5 8],[1 3 5 8],[1 2 5 7 8],[1 2 3 6 7],[3 4 7 8],[2 4 8 9],[2 4 5 9],[4 5 7 9],[2 6 7 8]};  k = length(data); = 1:k      data{i,1} = col1(i);      data{i,2} = col2{i};     data{i,3} = col3{i}; end data 

please, can code more efficiently written using form of indexing? thanks.

your have written code assign 9 x 3 cell array, can written as:

data2 = [num2cell(col1') col2' col3']  data2 =       [ 2]    [1x2 double]    [1x5 double]     [ 3]    [1x2 double]    [1x4 double]     [ 5]    [1x2 double]    [1x5 double]     [ 7]    [1x2 double]    [1x5 double]     [ 8]    [1x2 double]    [1x4 double]     [11]    [1x2 double]    [1x4 double]     [12]    [1x2 double]    [1x4 double]     [15]    [1x2 double]    [1x4 double]     [16]    [1x2 double]    [1x4 double]
