If I define a function like this
function [x, y] = findXY(B)
[by, bx] = size(B);
x = zeros(by,bx);
y = zeros(by,bx);
for i=1:10
x(i) = i;
y(i) = i;
end
end
I get the following error
The constructor for class 'findXY' must return only one output value.
Why is this happening? I can't use return values in a loop? I didn't find something similar while googling.
I have tried it:
[x, y] = findXY(ones(10,10))
and there is no problem. Could you give a more detailed explanation about where and how are you using it?
Probably the function is considered as constructor of a class - does it maybe sit in a directory named @TestXY?
And in this case, you are only allowed to return one object.
Maybe you could wrap your two return values into one cell array...
Something like
function xy = findXY(B)
[by, bx] = size(B);
x = zeros(by,bx);
y = zeros(by,bx);
for i=1:10
x(i) = i;
y(i) = i;
end
xy = {x y};
end
But if the function is not a constructor, your code is perfectly valid.
I will answer my question. The problem was a bit weird. I just restarted matlab and everything worked as expected. So if you walk into trouble and you cant find what is going wrong you should give restarting a try. It may work.
