How do I create this sorting function?
显示 更早的评论
Hi all. I am still a bit new to Matlab and I was asked to create a function with one input (X) and one output (Y) which ranks any set of numbers in such a way that for instance if X=[5 2 9 7], Y=[2 1 4 3]. This is to be done through the use of loops and logical operators. How would I go about doing this please? Thanks in advance.

For all unique values
input = [5 2 9 7];
output = sorting(input)
function y = sorting(x)
for i=1:numel(x)
y(i)=nnz(x(i)>=x); %you can use sum as well
end
end

numel(x) is defined as the prod(size(x))

Note: that sorting() function does not work if there are duplicate entries, and will return 0 for any entry that is NaN.
