Multiple Variable For Loop
显示 更早的评论
Hi
I have so far written this for loop
for i = 1:VgStep
for start = 1:VgStep:endPoint-VgStep+1
for step = VgStep:VgStep:endPoint
Vd{j}{i} = x(start:step);
Id{j}{i} = y(start:step);
end
end
end
I appologise for not explaining what all the terms are, but what I need is combine all those for's into one, because I end up just getting the same value for all my Vd{j}{i} terms
I'll explain better if it is needed

Can you give an example of what you want? All we have to go on is your code, which doesn't do what you want so we have to just guess. also, start and step are reserved words.

John, neither start nor step are reserved words. See http://www.mathworks.com/help/techdoc/ref/iskeyword.html

In the code posted, you do not have 'j' (this might be elsewhere in your code), in your example, not even sure why you need it.
Since you know what your step size is, you don't need to loop it, the way it is now, seems incorrect. This is what I see from your start:stop. When start > stop , you will get an empty index.
1:3, 1:6, 1:9, 4:3, 4:6, 4:9, 7:3 (error), 7:6 (error), 7:9
Do you understand how the following works?
i = 1;
for start = 1:VgStep:length(Vg) %what does this count?
Vd{i} = x(start:start+2); %try to understand the indexing here
Id{i} = y(start:start+2);
i=i+1; %how is this affected by 'start'?
end
