contour

Creates 2D contoured surface in an axes.

Syntax

contour(z)

contour(x, y, z)

contour(hAxes, ...)

Inputs

x, y, z: Range of the x, y, and z axes.; Type: double | integer; Dimension: scalar | vector | matrix
hAxes: Axis handle.; Type: double; Dimension: scalar

Example

Contour example:

cla;
x=[0:0.1:2*pi];
y=x;
z=sin(x')*cos(y);
contour(z)

Comments

If there are no axes, one will be created first. If x and y are omitted, the index of the columns of z is used for x coordinates and the index of the rows of z is used for y coordinates. If the first argument of contour() is an axes handle, surfaces will be created in that axes.
