Scilab Function

contour2d - level curves of a surface on a 2D plot

Calling Sequence

contour2d(x,y,z,nz,[style,strf,leg,rect,nax])
contour2d(x,y,z,nz,<opt_args>)

Parameters

Description

contour2d draws level curves of a surface z=f(x,y) on a 2D plot. The values of f(x,y) are given by the matrix z at the grid points defined by x and y .

You can change the format of the floating point number printed on the levels by using xset("fpf",string) where string gives the format in C format syntax (for example string="%.3f" ). Use string="" to switch back to default format and Use string=" " to suppress printing.

The optional arguments style,strf,leg,rect,nax , can be passed by a sequence of statements key1=value1, key2=value2 , ... where keys may be style , strf , leg , rect , nax . In this case, the order has no special meaning.

Use contour to draw levels curves on a 3D surface.

Enter the command contour2d() to see a demo.

Examples


contour2d(1:10,1:10,rand(10,10),5,rect=[0,0,11,11])
// changing the format of the printing of the levels
xset("fpf","%.2f")
clf()
contour2d(1:10,1:10,rand(10,10),5,rect=[0,0,11,11])
