function struct res = demos.VKOGA.VKOGA_1D_nD	(	integer	n,
		logical	fPGreedy,
		integer	nG
	)

static

Starts a demo of the approx.algorithms.VKOGA algorithm.

The functions all live on \([-5,5]\) for simplicity and can be of output dimension \(1-4\).

Parameters

n	The output space dimension. Between 1 and 4. Default: 1
fPGreedy	Flag to use f/P-Greedy instead of f-Greedy. Default: false
nG	The number of different \(\gamma\) values to use for the Gaussian. Default: 3

Return values

res	A struct with the fields {kexp, atd, alg} for further processing.
