Hey. Gays!
I wanna calculate pairwise euclidean distance and stack this Concatenate arrays vertically.
X = rand(7,7);
n = size(X,2);
for i=1:n
C = vertcat(pdist(X(:,i)));
end
I want to get the result (7 x 21) which was stacked.
However, I just got (1 x 21) matrix.
Does anyone have idea to fix this for loop code?

X = rand(7,7);
n = size(X,2);
C=cell(n,1);
for i=1:n
C{i}=pdist(X(:,i));
end
C=cell2mat(C);
