Hello,
Please help me with the following.
Consider a vector a=[2;3;3;5;5;5];
How can we replace the unique value "2" with the most populated one, i.e. "5".
The unique value can be found anywhere in the vector, in the above example it is shown as the first element.
The new vector should look like this:
b=[5;3;3;5;5;5];
Thank you very much.
Best,
Pavlos

a=[2;3;3;5;5;5];
c=unique(a);
ii=histc(a,c)
[idx1,idx1]=min(ii)
[idx2,idx2]=max(ii)
minv=c(idx1)
maxv=c(idx2)
b=a
b(a==minv)=maxv
%or
a=[2;3;3;5;5;5];
c=unique(a);
ii=histc(a,c)
[~,jj]=sort(ii)
a(a==c(jj(1)))=c(jj(end))
