2D vector field plot with colored arrows (obsolete)
champ1(x, y, fx, fy, [arfact, rect, strf])
- x, y
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
a matrix which describes the y component of the vector field.
fy(i,j)is the y component of the vector field at point
an optional argument of type
realwhich gives a scale factor for the display of the arrow heads on the plot (default value is 1.0).
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.

champ1 draws a 2D vector field with colored
arrows. The color of the arrows depends on the intensity of the
If you want arrows proportional to the intensity of the field, use

Be cautioned about the fact that using meshgrid function before
champ1 requires adjustment. For more details, see the last example below.
