Generating Array from nested loops
显示 更早的评论
So Ive been trying to create an array of 4 numbers using nested loops The first number goes from 1:5 The second number goes from 1:2 The third number goes from 1:3 The fourth number goes from 1:4
so that
A= [1 1 1 1
1 2 1 1
1 2 2 1
1 2 2 2
1 3 1 1
1 3 2 1
. . . .
. . . .
5 2 3 4 ]
So i been trying to use nested loops to generate that example
for n1 = 1: 5
n(n1,:) = [n1]
for n2 = 1: 2
n(n2,:) = [n2]
end
end
But this replaces my previous input. How do i make so i make that 4 element array of all possible values.
