Storing Outputs of a two output function recursion
显示 更早的评论
Is there a method where I can apply a function with two outputs, and iterate the function recursively for these two outputs. In other words, I want this function to be applied on both outputs of this function until satisfying a condition(in a while loop),
UPDATE:I tried the recursion provided here by Image analyst ,https://www.mathworks.com/matlabcentral/answers/47182-problem-in-recursive-function, it worked well, but I want to keep storing all the outputs in 1 cell structure, is it possible?

Yes. There is no limitation on the number of outputs for recursive function.

Like this? It is not a recursive fuction. Just while-loop
x=100;y=200;
k=0;
while x>1e-3 && y>1e-4
k=k+1
[x,y]=D23(x,y);
end
x
y
function [x,y]=D23(x,y)
x=x/2;
y=y/3;
end

Then it is not really an issue related to recursion. It is just storing data. The only thing to take care of is to declare a big enough arry or cell because the number of iteration is not determined. You can remove the un-used array space at the end.
x=100;y=200;
k=0;
result=ones(100,2);
while x>1e-3 && y>1e-4
k=k+1
[x,y]=D23(x,y);
result(k,:)=[x,y];
end
result(k+1:end,:)=[]
function [x,y]=D23(x,y)
x=x/2;
y=y/3;
end
