Displaying Contours in Polar Coordinates
You can contour data defined in the polar coordinate system. As an example, set up a grid in polar coordinates and convert the coordinates to Cartesian coordinates.
Then generate the complex matrix Z
on the interior of the unit circle.
X
, Y
, and Z
are points inside the circle.
Create and display a surface of the function .
Display the unit circle beneath the surface using the statements
Labeling the Graph
Contours in Cartesian Coordinates
These statements display a contour of the surface in Cartesian coordinates and label the x- and y-axis.
Contours on a Polar Axis
You can also display the contour within a polar axes. Create a polar axes using the polar
function, and then delete the line specified with polar
.
With hold
on
, display the contour on the polar grid.
