MATLAB: Finding Values From Arrays

Question

Hi Experts,

I have the following lines of code

I =

    I = imread(abc.jpg)
        [idx,C] = adaptcluster_kmeans(I);

idx =

            a     = unique(idx); //Unique values from idx e.g 1 2 3
            out   = [a,histc(idx(:),a)];//Frequency of unique value
            e.g
            1  18221
            2  28383
            3  18080
            [a,ix]= max(out(:,2)); //max unique value and its index
            a = 28383  ix = 2
Now what i want to do is to use this 'ix' and extract the corresponding pixel values and store them in an  excel file....

e.g ix = 2 in this case then i want to extract

Can any help how i can achieve this

Regards & Thanks

Hi rizwan

You can simply use the "find" command line.

[row column] = find(idx == ix)
