In kjohnsson/intrinsicDimension: Intrinsic Dimension Estimation

Description

Generates a sample from a certain anisotropic normal distribution centered around the origin.

Usage

 oblongNormal(Ns, n) 

Arguments

Ns	number of data points.
n	dimension of the distribution (and the data points).

In the first half of the dimensions (rounded down if n is odd) the standard deviation is 1 and in the rest the standard deviation is 0.25 .

Value

A Ns by n matrix.
