How to link loops together?

I am trying to make a program to get this numbers

0     1    0 
0    0.8  0.2
0    0.6  0.4
0    0.4  0.6
0    0.2  0.8
0     0    1
0.1  0.9   0
0.1  0.7   0.2
0.1  0.5   0.4
0.1  0.3   0.6
0.1  0.1   0.8
0.1   0    0.9

and so on but I cant make the program to reduce the values of the second and third column when the first column increases.

This is my code.

Thanks

lai=0:0.1:1;
laj=1:-0.2:0;
lat=0:0.2:1; 
for i=1,length(lai)
     for j=1,i
        for t=1,j
      j
      lam1(1,:)=lai;
     lam2(1,:)=laj;
     lam3(1,:)=lat;
          end
    end
end

The syntax for "for" loops is

for j=1:i

not

for j=1,i

The line you entered does have meaning: in particular it is the same as

for j = [1]
  i

which is to say that it would set j to 1 and then print out the value of i, and then after the rest of the statements in the body executed once the loop would be finished

Thanks I solved that problem but I don't know how to save the values of i into another variable. Or how to save the printed values. Can you help me with that too?
