Name
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.
