MATLAB: How to find the distance between vectors given in a cell array

Question

say i have a cell array in the form p = {[x1, y1], [x2, y2],…,[xn, yn]}

i want to find the number of points that arent within r distance of eachother. I know that pdist will find the distance between points but im not sure how to break this cell array up in order to apply this function. Any help?

Answer 1

You can apply pdist() like this

p = {[x1, y1], [x2, y2], [x3, y3]};
P = vertcat(P{:});
D = pdist(P);
