ezplot3

(Not recommended) Easy-to-use 3-D parametric curve plotter

collapse all in page

    ezplot3 is not recommended. Use fplot3 instead. For more information, see Version History.

    Syntax

    ezplot3(funx,funy,funz)
    ezplot3(funx,funy,funz,uinterval)
    ezplot3(___,'animate')
    ezplot3(ax,___)
    h = ezplot3(___)

    Description

    ezplot3(funx,funy,funz) plots the spatial curve defined by x = funx(u), y = funy(u), and z = funz(u) over the default interval [0,2π] for u.

    ezplot3 automatically adds a title and axis labels to the plot.

    example

    ezplot3(funx,funy,funz,uinterval) plots over the specified interval. Specify the interval as a two-element vector of the form [umin umax].

    ezplot3(___,'animate') produces an animated trace of the spatial curve. Use this option after any of the input argument combinations in the previous syntaxes.

    ezplot3(ax,___) plots into the axes specified by ax instead of the current axes. Specify the axes before any of the input argument combinations in any of the previous syntaxes.

    h = ezplot3(___) returns the plotted objects. Use h to modify properties of the plot after creating it.

    Open Live Script

    Plot this parametric curve over the domain [0,6π].

    x=sin(t),y=cos(t),z=t

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

    Figure contains an axes object. The axes object with title x = blank sin ( t ), blank y blank = blank cos ( t ), blank z blank = blank t, xlabel x, ylabel y contains an object of type line.

    Input Arguments

    collapse all

    Parametric function for x coordinates, specified as a character vector, string scalar, or function handle to a named or anonymous function.

    Specify a function of the form x = funx(u). The function must accept a vector input argument and return a vector output argument of the same size.

    When specifying the function as a character vector or string scalar, array multiplication, division, and exponentiation are always implied. For example, x^2 is interpreted as x.^2.

    Example: 'sin(2*u)'

    When specifying the function as a function handle, use array operators instead of matrix operators for the best performance. For example, use .* (times) instead of * (mtimes).

    Example: @(u) sin(2.*u)

    Parametric function for y coordinates, specified as a character vector, string scalar, or function handle to a named or anonymous function.

    Specify a function of the form y = funy(u). The function must accept a vector input argument and return a vector output argument of the same size.

    When specifying the function as a character vector or string scalar, array multiplication, division, and exponentiation are always implied. For example, x^2 is interpreted as x.^2.

    Example: 'cos(2*u)'

    When specifying the function as a function handle, use array operators instead of matrix operators for the best performance. For example, use .* (times) instead of * (mtimes).

    Example: @(u) cos(2.*u)

    Parametric function for z coordinates, specified as a character vector, string scalar, or function handle to a named or anonymous function.

    Specify a function of the form z = funz(u). The function must accept a vector input argument and return a vector output argument of the same size.

    When specifying the function as a character vector or string scalar, array multiplication, division, and exponentiation are always implied. For example, x^2 is interpreted as x.^2.

    Example: '2*u'

    When specifying the function as a function handle, use array operators instead of matrix operators for the best performance. For example, use .* (times) instead of * (mtimes).

    Example: @(u) tan(4.*u)

    Plotting interval for u, specified as a two-element vector of the form [umin umax].

    Axes object. If you do not specify an axes object, then ezplot3 uses the current axes (gca).

    R2016a: ezplot3 is not recommended

    ezplot3 is not recommended. Use fplot3 instead. There are no plans to remove ezplot3.

    fplot3 requires that the input functions to plot are function handles. ezplot3 accepts either function handles, character vectors, or strings. This table shows some typical usages of ezplot3 and how to update your code to use fplot3 instead.

    Not RecommendedRecommended
    ezplot3('sin','cos','t',[0 10])fplot3(@sin,@cos,@(t)t,[0 10])
    ezplot3('sin(t)','cos(t)','t',[0,6*pi])fplot3(@(t)sin(t),@(t)cos(t),@(t)t,[0,6*pi])
