Vector and Matrices comparison

Hi,

I want to find the closest column to a vector and name the index of the column?

V = 
0.320373395974224

What is your definition of closest?

[Ali Ali]

nearest column values to the vector

Answer 1

[Star Strider]

Use the pdist2 (link) function.

Example —

D = pdist2(V', N', 'euclidean','Smallest',1)
[~,ClosestCol] = min(D)

Note the transposition operators (').
