dat2sample:

Description

generates data elements according to SYN2 process (sample along a semi-sphere with additive noise, see reference).

Usage

dat2sample(nelts, radius, noise, oldbounds = NULL, newbounds = NULL)

Arguments

nelts

number of elements to generate.

radius

radius of the sphere to sample from.

noise

additive noise magnitude.

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.
