assign patterns to clusters

Hello,

Consider two vectors 1xm, namely vector1 and vector2 and three other ones of the same size, namely v1, v2 and v3.

I calclulate the distances (which don`t have to be the Euclidean),

d(vector1,v1)

d(vector1,v2)

d(vector1,v3)

and

d(vector2,v1)

d(vector2,v2)

d(vector2,v3)

How can I assign the vector1 and vector2 to a cluster with the minimum distance to v1, v2 or v3?

For example,

IF d(vector1,v2).le.d(vector1,v1) AND d(vector1,v2).le.d(vector1,v3) THEN assign vector1 to cluster 2.

I don`t mind doing it with "if-then" or "for-end" or any function.

Thank you.

Best,

Natasha

[mindist, minidx] = min([d(vector1,v1), d(vector1,v2), d(vector1,v3)], 2);

then minidx will be the cluster number.
