2D vector field plot
champ(x, y, fx, fy, [arfact, rect, strf]) champ(x, y, fx, fy, <opt_args>)
- 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
This represents a sequence of statements
key1=value1, key2=value2,... where
key2,... can be one of the following:
an optional argument of type
realwhich gives a scale factor for the display of the arrow heads on the plot (default value is
rect=[xmin, ymin, xmax, ymax]which gives the boundaries of the graphics frame to use.
a string of length 3 "xyz" which has the same meaning as the
plot2d. The first character
xhas no effect with
champ draws a 2D vector field. The length of
the arrows is proportional to the intensity of the field.
If you want colored arrows with the color of the arrows depending on
the intensity of the field, use
Enter the command
champ() to see a demo.
Be cautioned about the fact that using meshgrid function before
champ requires adjustment. For more details, see the last example below.
