How to obtain Euclidean Distance for multiple points?

After using the plotmatrix function to plot the graph. Is it possible to calculate the Euclidean Distance for the points ploted?

Answer 1

[Walter Roberson]

nx = size(X,2);
ny = size(Y,2);
dists = cell(nx, ny);
for yidx = 1 : ny
  for xidx = 1 : nx
    dists{xidx, yidx} = squareform( pdist( [X(:,xidx), Y(:,yidx)] ) );
  end
end

dists will now be a cell array of matrices, each of which is a square matrix giving the distance from every point in the column combination to each other point in that combination.

I had to assume here that your X and Y might contain multiple columns, since that is the main reason to use plotmatrix()

As you have data in hand you can use the formula of Euclidean distance....if you have multiple points have a look on pdist.
