squareNorm: Squared norm matrix calculation

Description Usage Arguments Value Author(s) See Also

View source: R/RcppExports.R

Description

This function gets the matrix of square norms which is needed for all kernels. Calculating this can help to save time if you are also interested in calculating the median heuristic, handling multiple tuning parameters or trying other kernels.

Usage

1
squareNorm(samples, nystrom_inds = NULL)

Arguments

samples

An N by d matrix of samples from the target

nystrom_inds

The (optional) sample indices to be used in the Nystrom approximation (for when using aSECF).

Value

An N by N matrix of squared norms between samples (or N by m where m is the length of nystrom_inds).
