Euclidean distance matrix

Computes the inter-site Euclidean distance matrix for one or two sets of points.

Usage

iDist(coords.1, coords.2, ...)

Arguments

coords.1

an \(n\times p\) matrix with each row corresponding to a point in \(p\) dimensional space.

coords.2

an \(m\times p\) matrix with each row corresponding to a point in \(p\) dimensional space. If this is missing then coords.1 is used.

...

currently no additional arguments.

Value

The \(n\times n\) or \(n\times m\) inter-site Euclidean distance matrix.
