MATLAB: How to process the output of fuzzy interface system(chance parameter) to select the indexes of first 3 maximum chance values??

chancefuzzy interface systemFuzzy Logic Toolbox

My project is " clustering in wireless sensor network using Fuzzy logic", Am doing this for 60 nodes. In this project the node with the maximum chance value will become the cluster head. the chance values for all 60 node is stored in the array variable "LQ", i need to select the 3 cluster head with maximum chance parameter to do this i need the indexes of the first 3 maximum chance parameter. here i need the indexes value……

Ok, I see, not really a Fuzzy Logic question, more of a basic MATLAB question.

x=rand(60,1); %test vactor of 60 random numbers
[svals,idx]=sort(x,'descend'); %sort in descending order
svals(1:3) %the 3 largest values
idx(1:3) % the indices of 3 largest values

MATLAB: How to load multiple files and do the computation for each of them and write the output in consequent rows

Your loop will want to start with grabbing all files in a folder. uigetfile with the MultiSelect option will work wonders here:

[Name,Path]=uigetfile({'*.xlsx*'},'MultiSelect','on');
entirefile=fullfile(Paths,Names);

Then start your loop. It wants to run a number of times equal to the number of elements in your entirefile cell, as you also have in your own code. Within this loop, do all your loading, calculation and writing. To avoid cluttering the workspace, you might want to look into a structure and dot indexing.

for i=1:numel(entirefile);
    %your entire code including
    enginedata(i).raw=importdata(entirefile{i});
    enginedata(i).temperature = your temperature calculation
    enginedata(i).oilpressure = oil pressure calculation
    %and so on
    %finally, to write in consecutive fields the results, simply keep indexing your things:
    celltarget=['B',num2str(i)]; %B1 first run, B2 2nd run etc. 
    writecell(mean_engine_temperature,filename,'Sheet','Temperatures','Range',celltarget);
end

c(1,:)=[0 0 1] % blue color
c(2,:)=[1 0 0]  % red
c(3,:)=[0 1 0] % green
y=[185 145 30;123 100 14 ;65 67 NaN]; 
h=bar(y,1)
set(h,{'FaceColor'},num2cell(c,2))
