Pairwise Euclidean distance between two set of vectors

Contents

Syntax

Description

distPairwise(mat1, mat2) returns the distance matrix between two set of column vectors mat1 and mat2.

The element at row i and column j of the return matrix is the Euclidean distance between column i of mat1 and column j of mat2.

Example

mat1=[1 3 3;2 3 4];
mat2=[4 5 6 7;3 3 4 5];
fprintf('mat1 =\n'); disp(mat1);
fprintf('mat2 =\n'); disp(mat2);
out=distPairwiseM(mat1, mat2);
fprintf('distPairwise(mat1, mat2) =\n'); disp(out);

mat1 =
     1     3     3
     2     3     4

mat2 =
     4     5     6     7
     3     3     4     5

distPairwise(mat1, mat2) =
    3.1623    4.1231    5.3852    6.7082
    1.0000    2.0000    3.1623    4.4721
    1.4142    2.2361    3.0000    4.1231
