Replace values with specified values

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

    dF =
         6    10
         8    13
         6     5
         8    10
         6    13
         8     5

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?
