peaks

---

Peaks function

---

Syntax

---

Z = peaks()

Z = peaks(n)

Z = peaks(Xi, Yi)

[X, Y, Z] = peaks()

[X, Y, Z] = peaks(n)

[X, Y, Z] = peaks(Xi, Yi)

Input argument

---

n

Value representing 2-D grid: scalar or vector.

Xi

x-coordinates of points.

Yi

y-coordinates of points.

Output argument

---

X

x-coordinates of points.

Y

y-coordinates of points.

Z

z-coordinates of points.

Description

---

peaks function has the form:

f(x, y) = 3*(1-x)^2*exp(-x^2 - (y+1)^2) - 10*(x/5 - x^3 - y^5)*exp(-x^2-y^2) - 1/3*exp(-(x+1)^2 - y^2)

Example

---

x = -2:0.5:2;
y = 1:0.2:2;
[X, Y] = meshgrid(x, y);
Z = peaks(X, Y)
