PEAKS

Purpose:

Generates a Gaussian function of two variables, z = f(x, y).

PEAKS(n)

PEAKS(x, y)

n	-	Optional. An integer, the n x n output array size.
x	-	Optional. A real, the X value.
y	-	Optional. A real, the Y value.

peaks(n)

returns an array.

peaks(x, y)

returns a scalar.

W1: peaks()

W2: peaks(20)

W1 contains the default 49 x 49 surface.

W2 contains a 20 x 20 surface.

peaks(1, 1)

returns 2.433789, the value of Z at X = 1.0, Y = 1.0

Peaks generates a Z surface of scaled and translated Gaussians.

The function of X and Y is :

where the default X and Y range is -3..(1/8)..3
