VBmix (version 0.3.2)

dat3sample:

Description

generates data elements according to SYN3 process (sample along a 2D circle with additive noise, and linearly transform to higher dimensional space with further noise addition, see reference).

Usage

dat3sample(nelts, radius, noise, transform=generate2Dtransform(2), 
	oldbounds = NULL, newbounds = NULL)

Arguments

nelts

number of elements to generate.

radius

radius of the sphere to sample from.

noise

additive noise magnitude.

transform

matrix defining linear transform. Defaults to I.

oldbounds

optional argument for sample rescaling. If not NULL, transmitted to setDomain as oldspan.

newbounds

optional argument for sample rescaling. If not NULL, transmitted to setDomain as newspan.

Value

matrix of sampled row-elements.
