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 want to find distance between 1st column of A matrix and 1st column of Y matrix which leads to one single value as solution. similarly for 2nd and 3rd column by applying eucliden distance
After calculating we should get 3 values.
C=[x y z]
How can we proceed this?

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?

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
