- Since pdist() accepts matrix as an argument, you should convert cell array to matrix using cell2mat function
- Find pair wise distances using pdist() function
- Count number of distances greater than r distance.

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?

Below are the few steps which may help you.
Example-
p={[1,2],[3,4],[5,6],[7,8]};
matrixP=cell2mat(p(:));
distance = pdist(matrixP);
sum(distance>3)
