I have a full factorial design array and certain levels

      a = [6,8]
      b = [10,13,5]
     dF = fullfact([2 3])
      =
         1     1
         2     1
         1     2
         2     2
         1     3
         2     3

I would like to replace the values [1,2] of the first column with a and in the second [1,2,3] with b so that

Is there an easy way to do it? I'll need it for a 388800x10 full factorial with up to 12 different levels for each column, so I cannot replace all values one by one.

I answered the (somewhat) same question yesterday, this should solve your issue:

This makes sense if you only have three levels. I have a 388800x10 full factorial with up to 12 different levels for each column. Is there a shorter way?

a = [6,8];
b = [10,13,5];
ffPlan = fullfact([2, 3]);
parPlan = zeros(size(ffPlan));
parPlan(:,1) = a(ffPlan(:,1));
parPlan(:,2) = b(ffPlan(:,2));
disp(parPlan)
     6    10
     8    10
     6    13
     8    13
     6     5
     8     5
