D=fullfact(4*ones(1,6));

fullfact returns the design levels as 1:L; to have as wanted levels since they're all same for each factor

>> D(1:5,:)
ans =
     1     1     1     1     1     1
     2     1     1     1     1     1
     3     1     1     1     1     1
     4     1     1     1     1     1
     1     2     1     1     1     1
>> L=[-0.5 -0.3 0.3 0.5];
>> D=L(D);
>> D(1:5,:)
ans =
   -0.5000   -0.5000   -0.5000   -0.5000   -0.5000   -0.5000
   -0.3000   -0.5000   -0.5000   -0.5000   -0.5000   -0.5000
    0.3000   -0.5000   -0.5000   -0.5000   -0.5000   -0.5000
    0.5000   -0.5000   -0.5000   -0.5000   -0.5000   -0.5000
   -0.5000   -0.3000   -0.5000   -0.5000   -0.5000   -0.5000
