Using pdist with two matrix's
显示 更早的评论
Hi,
So if I have one 102x2 matrix of x,y coordinates, and another 102x2 matrix of x,y coordinates, can pdist be used to compare all the rows in matrix 1 with the rows in matrix 2? As in for matrix one row 1, the x,y coordinates are compared to matrix 2 row 1 x,y coordinates; row 2 mat1 is compared to row 2 mat2 etc to find the distance between them, for all 102 rows?
I want to find their distances but I can't quite understand the help page on pdist, can it be used for this or is there another function I should look at?
Many thanks!

Use pdist2()
distances = pdist2(xySet1, xySet2);

Then just use sqrt():
distances = sqrt((xy1(:, 1) - xy2(:, 1)) .^ 2 + (xy1(:, 2) - xy2(:, 2)) .^ 2)
Basically it's just distances = sqrt(deltax^2 + deltay^2)
