Description
Plots a function over the specified region.
Inputs
| Name | Description | ||||||||||||||||||||||||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| f, fx, fy | Specifies the function you want to plot. f is a string that represents a function of one or two variables. If f is an expression of a single variable x, plotf plots y = f(x). If f is an expression of two variables x and y, plotf plots f(x, y) = 0. If you specify fx and fy, plotf plots fx and fy as the parametrically defined planar curve (fx(t), fy(t)). | ||||||||||||||||||||||||||||||||||
| r | Specifies the region of the plot. If f is a parametrically defined planar curve, the default is [0, 2*pi]. Otherwise, the default is [-2*pi, 2*pi]. | ||||||||||||||||||||||||||||||||||
| attributes | Specifies valid plot attributes. Order the plot attributes by color, point style, and line style. For example, 'bo-' specifies that the plot is blue, marks points with circles, and uses solid lines. attributes is a string that accepts a combination of the following values.

Examples
f = 'sin(x)';
plotf(f)
fx = 'sin(sinc(t*t))*cos(t)';
fy = 'sin(sinc(t*t))*sin(t)';
plotf(fx, fy)
f = 'x^2+y^2-1';
r = [-1.2, 1.2, -0.8, 0.8];
plotf(f, r)
