Dear Matlab users,
I am trying to write a program with a loop. Assume that for each of the element of L, there are two solutions of M, and two solutions of N. I want to write them all on a table.
L=[1,2]'
M=[10,20,60,70]'
N=[100,200,500,600]'
Table=[
L(1) M(1) N(1)
L(1) M(1) N(2)
L(1) M(2) N(1)
L(1) M(2) N(2)
L(2) M(3) N(3)
L(2) M(3) N(4)
L(2) M(4) N(3)
L(2) M(4) N(4)]
Table should be like this. However, L vector doesn't have to have two elements. It might have more elements. If L has the third element for instance, the next line would be L(3) M(5) N(5).
Can you recommend how to write a Matlab code to generate this table?
Thanks in advance

Ran in:
In your case, you'd need to use hand entry. However, if your pattern is repeating then, you can employ replem() and get these.
L=[1, 2]'; L=repelem(L,4);
M=[10,20,60,70]'; M=repelem(M,2);
N=[100,200,500,600]'; N=repelem(N,2);
T= array2table([L, M, N], 'VariableNames', {'L', 'M', 'N'})
T = 8×3 table
L M N _ __ ___ 1 10 100 1 10 100 1 20 200 1 20 200 2 60 500 2 60 500 2 70 600 2 70 600

Try this:
Col1 = repelem(L,4);
Col2 = repmat(M',2,1);
Col3 = repmat([N(1:2:end),N(2:2:end)]',2,1);
Table = [Col1 Col2(:) Col3(:)];
