How to find euclidean distances of each column of the two matrices?

19 views (last 30 days)
I have two matrices X and Y, of order 5*3 order
I want to find euclidean distance of 1st column of X matrix and 1st column of Y matrix. Subsequently for 2nd and 3rd column of X and Y matrix.
The solution should be in 1*3 order. How can we proceed this problem?
pdist2(xySet1, xySet2); This solution is for solving eucliden distance of each row of X and Y.
I want to find their distances of each column of the two matrices but I can't understand the help page on pdist.

I don't understand what you expect to happen, so I hope the solutions below will help.
For 5 pairs of x and y you expect a single distance. What is the distance between 5 points? The solutions below assume you want the sum of the 4 subsequent distances. Do you?

A= [0.5958 0.8909 0.9135
0.5348 0.0558 0.4093
0.0265 0.1159 0.8576
0.0066 0.1568 0.8366
0.4693 0.2467 0.2841];
B= [0.4251 0.2552 0.8203
0.3655 0.3306 0.3039
0.4244 0.4263 0.1493
0.4422 0.3184 0.2394
0.0107 0.1467 0.8425];
d = vecnorm(A-B)
d = 1×3
0.7850 0.7824 1.0908

Hi ,
You can do like this:
A = [1 2;3 4]
A = 2×2
1 2 3 4
B = [4 2;7 4]
B = 2×2
4 2 7 4
Distance1 = sqrt(sum((A - B) .^ 2))
Distance1 = 1×2
5 0
