Use examples:

C + + code

Mgldata A (50,40);
A.modify ("0.6*sin (2*pi*x) *sin (3*pi*y) + 0.4*cos (3*pi* (x*y))");
Gr->rotate (40,60);
Gr->box (); Gr->light (TRUE); Gr->fog (1,0.1);
Gr->surf (a); Gr->c++ont (A, "Y");

MGL Code

New A 50 40
Modify a ' 0.6*sin (2*pi*x) *sin (3*pi*y) + 0.4*cos (3*pi* (x*y))
Rotate 40 60
Box:fog 1 0.1:light on
Surf A:cont a ' y '

Pure C Code

Hmdt a = Mgl_create_data_size (50,40,1);
Mgl_data_modify (A, "0.6*sin (2*pi*x) *sin (3*pi*y) + 0.4*cos (3*pi* (X*y))", 0;

Mgl_rotate (gr,40.,60.,0);
Mgl_box (gr,1);
Mgl_fog (gr,1.,0.1)
Mgl_light (gr,1)
Mgl_surf (gr,a,0);
Mgl_cont (gr,a, "Y", 7,nan);
Mgl_delete_data (a);

Fortran Code

Integer A, mgl_create_data_size
Real Zero, Nan
! I don ' t know the NaN symbol in Fortran. So I produce it as Zero/zero
Zero = 0; Nan = Zero/zero
A = Mgl_create_data_size (50,40,1);
Call Mgl_data_modify (A, "0.6*sin (2*pi*x) *sin (3*pi*y) + 0.4*cos (3*pi* (X*y))", 0;

Call Mgl_rotate (gr,40.,60.,0.)
Call Mgl_box (gr,1)
Call Mgl_fog (gr,1.,0.1)
Call Mgl_light (gr,1)
Call Mgl_surf (Gr,a, "")
Call Mgl_cont (gr,a, ' y ', 7,nan)
Call Mgl_delete_data (a)

Python

A = Mgldata (50,40);

Gr. Rotate (40,60);
