save only one value
显示 更早的评论
Hello,
I have for example matrix
MON = [2.8 3.6 17.2;
5.4 8.3 15.8;
2.5 3.2 17.6;
9.9 10.7 13.6;
5.5 8.9 15.5;
9.7 11 13.9;
2.3 3.9 17.9;
5.7 8.1 15.1;
9.4 10.5 13;
9.9 13.2 13.7];
I calculate distance between points from MATRIX.
or i=1:m % pre pocet objektov (pre kazdy riadok MON)
B = MON(i,:); % vloz i-ty riadok z MON do premennej B
for j=1:r % pre kazdy riadok TAZ
ED(j)= distance(TAZ(j,:),B,fff); %euklidovska vzdialenost
[minD, minI(idx)] = min([ED]); %minimalna hodnota a index
end
Then I want to save the smallest value to the cell.
[e,f]=size(ED);
for h=1:f
if (ED(h) == ED(minI(idx)))
Z{h}{z}=B;
z=z+1;
end
end
idx=idx+1;
end
If I have the same value is stored me both to cell. How i stored a just a single valu to cell.
For example ED=[4 4 6] I want only values from position ED(1) save to cell.
Thanks.

Why a cell instead of a regular numerical array which is much much easier to work with?

Sorry, but even your English is a bit confusing, just like mine! lol Is the problem of having two 4 bothers you?
If so then I guess you can use 'unique' to get rid of the repeated 4
ED= unique(ED,'stable') % this should give you ED=[4,6]
Sorry if I didn't get what's your problem, please explain more what do you want to happen.
Good Luck!

OK! So your English is ok, because I understood you problem I just thought I didn't.
Have you tried the command the I suggested you in the answer above?
ED= unique(ED,'stable') %
I believe this will solve your problem.
Good Luck!

Are you sure the error is not for something else rather than
ED= unique(ED,'stable') %
Put your code and the error you get for running the code

First of all so sorry for getting back to you with a huge delay, you're problem is probably solved by now! so sorry
I read through the MATLAB help for 'unique()' and unfortunately it's clearly documented that 'unique treats NaN values as distinct'
So for your example we can't use unique anyway!
If the problem is only with NaN then it's easy
i=1;
NanCount=0;
while(i<= length(ED))
if(isnan(ED(i)))
if(NanCount>0)
ED(i)=[];
i=i-1;
end
NanCount=NanCount+1; % to see how many nan is omitted
end %end of if
i=i+1;
end %end of while
Number of omitted NaNs should equal NanCount-1
Sorry I don't have MATLAB now to try it. Give it a shot and let me know about the result.
