MATLAB Function Reference
ezplot3

Easy to use 3-D parametric curve plotter

Syntax

• ```ezplot3(x,y,z)
ezplot3(x,y,z,[tmin,tmax])
ezplot3(...,'animate')
```

Description

`ezplot3(x,y,z)` plots the spatial curve x = x(t), y = y(t), and z = z(t) over the default domain 0 < t < 2.

`ezplot3(x,y,z,[tmin,tmax])` plots the curve x = x(t), y = y(t), and z = z(t) over the domain `tmin` < t < `tmax`.

`ezplot3(...,'animate')` produces an animated trace of the spatial curve.

Remarks

Array multiplication, division, and exponentiation are always implied in the expression you pass to `ezplot3`. For example, the MATLAB syntax for a plot of the expression,

• ```x = s./2, y = 2.*s, z = s.^2;
```

which represents a parametric function, is written as:

• ```ezplot3('s/2','2*s','s^2')
```

That is, `s/2` is interpreted as `s./2` in the string you pass to `ezplot3`.

Examples

This example plots the parametric curve,

over the domain [0,6]:

• ```ezplot3('sin(t)','cos(t)','t',[0,6*pi])
```
