2D vector field plot with colored arrows (obsolete)
champ1(x, y, fx, fy, [arfact, rect, strf])
two vectors which define the grid.
a matrix which describes the x component of the vector
field. fx(i,j)
is the x component of
the vector field at point (x(i),y(j))
.
a matrix which describes the y component of the vector
field. fy(i,j)
is the y component of
the vector field at point (x(i),y(j))
.
an optional argument of type real
which gives a scale factor for the display of the arrow
heads on the plot (default value is 1.0).
a vector rect = [xmin, ymin, xmax, ymax]
which gives the boundaries of the graphics frame to use.
controls the computation of the actual coordinate ranges from the minimal requested values. The associated value should be an integer ranging from 0 to 8.
specifies how the axes are drawn. The associated value should be an integer ranging from 0 to 5.
a string of length 3 "xyz" which has the same meaning as
the strf
parameter of plot2d
.
The first character x
has no effect
with champ1
.
![]() | champ1() is obsolete and will be removed from Scilab 6.1.x .
Please use the champ().colored property instead. |
champ1
draws a 2D vector field with colored
arrows. The color of the arrows depends on the intensity of the
field.
If you want arrows proportional to the intensity of the field, use
champ
.
Enter the command champ1()
to see a demo.
Be cautioned about the fact that using meshgrid function before
using champ1
requires adjustment. For more details, see the last example below.
// using meshgrid to get fx and fy clf() x = linspace(-1,1,30); y = linspace(-1,1,30); [X,Y] = meshgrid(x,y); fy = 2.*Y; fx = 2.*X; champ1(x,y,fx',fy'); //here we have transposed fx and fy | ![]() | ![]() |
