frobenius_norm_funct_multiv: Functional multivariate Frobenius norm

In adamethods: Archetypoid Algorithms and Anomaly Detection

Description

Computes the functional multivariate Frobenius norm.

Usage

frobenius_norm_funct_multiv(m, PM)

Arguments

m	Data matrix with the residuals. This matrix has the same dimensions as the original data matrix.
PM	Penalty matrix obtained with eval.penalty.

Details

Residuals are vectors. If there are p variables (columns), for every observation there is a residual that there is a p-dimensional vector. If there are n observations, the residuals are an n times p matrix.

Value

Real number.
