fplot3d1

3D gray or color level plot of a surface defined by a function

Calling Sequence

fplot3d1(xr,yr,f,[theta,alpha,leg,flag,ebox])
fplot3d1(xr,yr,f,<opt_args>)

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 plot3d1. : :<opt_args> see plot3d. :

Description

fplot3d1 plots a 3D gray or color level plot of a surface defined by the external function f on the grid defined by xr and yr.
