Returns the point-to-point distance between all pairs ...

Returns the point-to-point distance between all pairs of points (similar to PDIST in the Statistics Toolbox, for those without it)
DMAT = DISTMAT(XY) Calculates the distance_matrix by Joseph Kirk using an automatic option
DMAT = DISTMAT(XY, OPT) Uses the specified option to compute the Distance Matrix 1.0
[DMAT, OPT] = DISTMAT(XY) Also returns the automatic option used by the function
Inputs:
XY is an NxP matrix of coordinates for N points in P dimensions
OPT (optional) is an integer between 1 and 4 representing the chosen method for computing the Distance Matrix [distancematrix1.0.exe] (see note below)
Outputs:
DMAT is an NxN matrix, where the value of DMAT(i, j) corresponds to the distance from XY(i, :) to XY(j, :)
OPT (optional) is an integer between 1 and 4 representing the method used to compute the Distance Matrix - 0MB (see note below)
Note:
DISTMAT contains 4 methods for computing the Distance Matrix 1.0
OPT=1 Usually fastest for small inputs. Takes advantage of the symmetric property of distance matrices to perform half as many calculations
OPT=2 Usually fastest for medium inputs. Uses a fully vectorized method
OPT=3 Usually fastest for large inputs. Uses a partially vectorized method with relatively small memory requirement
OPT=4 Another compact calculation, but usually slower than the others
Demands:
• MATLAB Release: R2007a
