VBmix (version 0.3.2)

dat1sample:

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
