In linulysses/matrix-manifold: Basic Operations and Functions on Matrix Manifolds

Description

Generate a set of random matrices that represent tangent vectors at some point.

Usage

## S3 method for class 'spd_LogEuclidean'
rtvecor(mfd, n = 1, sig = 1, drop = T)

Arguments

mfd	an object created by matrix.manifold
n	sample size
sig	the standard deviation of the normal distribution
drop	whether return the result as a matrix when n=1

Details

The generated samples have expectation zero and follow a isotropic D-dimensional normal distribution with isotropic variance sig, where D is the intrinsic dimension of the matrix manifold

Value

an M*N*n array of n matrices, where M*N is the dimensions of matrices
