fplot3d

3D plot of a surface defined by a function

Syntax

fplot3d(xr,yr,f,[theta,alpha,leg,flag,ebox])
fplot3d(xr,yr,f,<opt_args>)
h = fplot3d(...)

Arguments

xr: row vector of size n1.
yr: row vector of size n2.
f: external of type z=f(x,y).
theta,alpha,leg,flag,ebox: see plot3d.
<opt_args>: see plot3d.
h: This optional output contains a handle to a Plot3d. Use h to modify its properties. For a list of properties, see surface_properties.

Description

fplot3d plots a surface defined by the external function f on the grid defined by xr and yr.

Enter the command fplot3d() to see a demo.

Examples

deff('z=f(x,y)','z=x^4-y^4')
x=-3:0.2:3 ;y=x ;
clf() ;fplot3d(x,y,f,alpha=5,theta=31)
