Hi everyone, I got a question when using pdist function in Matlab, it would be so many thanks if you could give me some advice. The pdist(D) usually gives the sum of the distance of the multiple dimension (Euclidean distance), however, I want to get the distance separately. For example I have a data set S which is a 10*2 matrix , by using pdist(S(:,1)) and pdist(S(:,2)) to get the distance separately, but this seems very inefficient when the data has many dimensions. Is there any alternative way to achieve this more efficient? Thanks in advance!
