`fplot3`

Plots a 3-D parametric curve from three coordinate functions given as handles.

Syntax

fplot3(funx, funy, funz)

Plots (funx(t), funy(t), funz(t)) over the default range [-5 5] of t.

fplot3(funx, funy, funz, [tmin tmax])

Uses the given range of t.

fplot3(___, LineSpec)

Sets color, style and marker.

h = fplot3(___)

Also returns the line handle.

Description

Like fplot, it adds sample points where the curve bends, so you do not have to choose a step. It is the function-handle counterpart of plot3 and replaces ezplot3.

Input arguments

funx, funy, funz: Function handles of t that accept vectors.
[tmin tmax]: Range of the parameter.

Output arguments

h: Handle to the 3-D line.

Example

Conical spiral

fplot3(@(t) t.*cos(t), @(t) t.*sin(t), @(t) t, [0 10*pi])
grid on

In the app, the figure is drawn below the code.
