dat1sample: dat1sample

In VBmix: Variational Bayesian Mixture Models

Description

generates data elements according to SYN1 process (sample from a 2D GMM, linearly transformed with additive noise, see reference).

Usage

dat1sample(nelts, gmm, noise, transform=generate2Dtransform(2), 
	oldbounds = NULL, newbounds = NULL)

Arguments

nelts	number of elements to generate.
gmm	2D GMM to be sampled 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
