fplot3d - 3D plot of a surface defined by a function

Calling Sequence

fplot3d(xr,yr,f,[theta,alpha,leg,flag,ebox])

fplot3d(xr,yr,f,<opt_args>)

Parameters

• 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 .

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)
