How to apply distance formula on n-number of input data sets?

Hi there,

I am trying to apply eucledian distance fromula on different data sets but I am confused about the logic.

Let me tell you about the situation first.

let's say I have 5 data sets as follow

data1 = randn(2,11); data2 = randn(2,11); data3= randn(2,11); data4 = randn(2,11); data5 = randn(2,11);

I want the distances to be calculated in the following manner:

({data1, data2},{data1, data3},{data1,data4},{data1,data5},{data2,data3}....... {datan,datan})

I don't know how to do it?

Basically I have around 2 million airfoil shapes and I wanted to calculate the distances between all of them.

I hope you are getting what I am saying!

The “pdist” function can be a potential workaround to the above issue. The function “pdist” provides the pairwise distance between pairs of observations. Refer the link below to know more about “pdist” function.
