Hello, can anyone help me with this one? I have this array called 'd'. I want to generate a new array called ratio. Answers for array ratio should be calculated as the given example. d1,d2,... are numbers in descending order. I have around 100 numbers in array d. So I am trying to run a code to do the calculations automatically. Thank you.
d=[d1;d2;d3;d4] % example d=[4;3;2;1]
size=length(d)
ratio=zeros(size,size-1)
%calculations
ratio=[0 0 0 ;
d1/d2 0 0 ;
d1/d3 d2/d3 0 ;
d1/d4 d2/d4 d3/d4 ]

try this
d = [4 3 2 1];
ratio = tril(d./d.', -1);
ratio(:,end) = [];
Result:
ratio =
0 0 0
1.3333 0 0
2.0000 1.5000 0
4.0000 3.0000 2.0000
