contour(2) Scilab Function contour(2)
NAME
contour - level curves of surface
CALLING SEQUENCE
contour(x,y,z,nz,[theta,alpha,caption,flag,bbox,zlev])
contour2d(x,y,z,nz,[style,strf,leg,rect,nax])
PARAMETERS
x,y : two real vectors of size respectively (1,n1) and (1,n2).
z : real matrix of size (n1,n2) (values)
nz : real vector of size > 1 (the level values) or an integer ( the
number of level curves ).
flag : is a real vector of size three [mode,type,box]
zlev : real number
[theta,alpha,caption,flag,bbox,zlev]
: see plot3d
[style,strf,leg,rect,nax]
: (see plot2d). The argument style gives the dash styles or
colors which are to be used for level curves. It must have the
same size as the requested level curves. The other arguments fol-
lows the rules given in plot2d.
DESCRIPTION
Draws level curves of a surface z=f(x,y). The level curves can be drawn on
a 3D surface or on 2D plot. For level curves on a 2d plot, the function
contour2d should be preferred to the function contour since it accepts
standard 2d parameters [style,strf,leg,rect,nax]. for level curves on a 3d
plot, the optional arguments are the same as for the function plot3d
(except zlev ) and their meaning are the same. They control the drawing of
level curves on a 3D plot. Only flag(1)=mode has a special meaning.
mode=0 : the level curves are drawn on the surface defined by
(x,y,z)
mode=1 : the level curves are drawn on a 3D plot and on the plan
defined by equation z=zlev
mode=2 : The level curves are drawn on a 2D plot.
Enter the command contour() to see a demo.
EXAMPLE
contour2d(1:10,1:10,rand(10,10),5,1:5,"011"," ",[0,0,11,11]);
