Input-Looping Matrix Dimensions Must Agree

1 次查看(过去 30 天)
I got this error in very early morning:
Error using - Matrix dimensions must agree.
Error in DistMatrix3 (line 23)
d=sqrt((I-L').^2+(J-M').^2+(K-N').^2);
Error in coba (line 20)
d=DistMatrix3(cobat,c); % calculate the distance
And here is the code of mine: load cobat.txt
k=input('Enter a number: ');
[maxRow, maxCol]=size(cobat);
for i=1:k
for j=1:maxCol
c=input('Enter a number: '); % sequential initialization
end
end
temp=zeros(maxRow,1); % initialize as zero vector
u=0;
while 1,
d=DistMatrix3(cobat,c); % calculate the distance
[z,g]=min(d,[],2); % set the matrix g group
if g==temp, % if the iteration doesn't change anymore
break; % stop the iteration
else
temp=g; % copy the matrix to the temporary variable
end
**for i=1:k
f=find(g==i);
if f % calculate the new centroid
c(i,:)=mean(cobat(find(g==i),:),1);**
end
end
end
y=[cobat,g]
I think the error isn't because the DistMatrix3 itself. It is caused by 'c' inputs. the looping-input. And I guess these lines that should be fixed since it doesn't contain 'j' variables:
for i=1:k
f=find(g==i);
if f % calculate the new centroid
c(i,:)=mean(cobat(find(g==i),:),1);
end
I'm stuck how I should fix it. Can you guys tell me what should I do to solve this this? Your help will be much appreciated.
Thank you.

I am using this code but not understood about number of iteration i.e how many iteration are there in the code
