Introduction to MATLAB drawing functions ezplot explanation

I. Introduction
The ezplot command can be used to draw the graph of the explicit function, the graph of the implicit function, or the graph of the function determined by the parameter equation, and the system will automatically add the title of the graph, xaxis labels.While fplot is mainly used to draw graphs of explicit functions and functions determined by parametric equations, fimplicit is mainly used to draw graphs of implicit functions.So from a functional point of view, ezplot covers the fplot and fimplicit functions.However, it is not as convenient as fplot and fimplicit to use ezplot to set the color and other attributes of primitives, and you need to use set to set them.If multiple curves are drawn in a graphics window, the system automatically assigns the last function to be the title of the graph, resulting in ambiguity. You need to manually use the title command to add the title.
Second, the basic syntax of ezplot
1) Draw the graphics of the explicit function (I):

ezplot( function, interval )

Its function is to draw the graph of the explicit function function on the interval interval. When the interval is default, the interval is -2π < x < 2π .The format of interval is [ min, max ].
2) Drawing the graph of the explicit function (II):

ezplot( @(varible)function, interval )

The parameter variable variable is explicitly specified.Its function is to draw the graph of the explicit function function with varible as the independent variable on the interval interval. When the interval is default, the interval is -2π < x < 2π .The format of interval is [ min, max ].
3) Draw the graph of the implicit function (I):

ezplot( function, xyinterval )

Its function is to draw the graph of the implicit function determined by the equation function=0 on the interval xyinterval. When xyinterval is default, the interval is -2π < x < 2π , -2π < y < 2π .The format of xyinterval is
[ xmin, xmax, ymin, ymax ].
4) Draw the graph of the implicit function (II):

ezplot( @(varibles)function, xyinterval )

Its function is to draw the graph of the implicit function with varibles as 2 variables and determined by the equation function=0 on the interval xyinterval. When xyinterval is default, the interval is -2π < x < 2π , -2π < y< 2π .The format of xyinterval is [ xmin, xmax, ymin, ymax ].
5) Plot the graph of the parametric equation to determine the function (I):

ezplot( xfun, yfun, tinterval )

Its function is to draw the graph of the function determined by the equation xfun=0, yfun=0 on the interval tinterval to which the parameter belongs. When tinterval is default, the interval is 0 < t < 2π.
6) Plot the graph of the parametric equation to determine the function (II):

ezplot( @(variable)xfun, @(variable)yfun, tinterval )

The parameter variable variable is explicitly specified.Its function is to draw the graph of the function determined by the equation xfun=0, yfun=0 on the interval tinterval to which the parameter belongs. When tinterval is default, the interval is 0 < t < 2π.
3. Specific examples
Example 1. Draw the curve of the function y=sin(x).

% sample codeh = ezplot( 'sin(x)', [ 0, 2 * pi ] );set( h, 'LineStyle', '-.', 'color', 'r', 'LineWidth', 2 );% set primitive properties

%Running result

Example 2. Drawing functionThe curve of y=sin(1/x).

% sample codeezplot( @(x)sin(1./x) );

%Running Results

Example 3. Drawing equationThe curve represented by x^2 + y^2 = 1.

% sample codeezplot( @(x,y)x.^2 + y.^2 - 1, [ -1, 1, -1, 1 ]);axis equalaxis( [ -1.5, 1.5, -1.5, 1.5 ] )

%Running result

Example 4. Draw byThe curve represented by the parametric equation x=ρcos(t),y = ρsin(t).

% sample codeezplot( @(t)cos(t), @(t)sin(t), [ 0, 2*pi ]);axis equalaxis( [ -1.5, 1.5, -1.5, 1.5 ] )

% Run result

Example 5. In aThe graphics window plots the functions y=sin(x) and y=cos(x).

% sample codeezplot( 'sin(x)', [ 0, 2 * pi ] );hold onezplot( 'cos(x)', [ 0, 2 * pi ] );

% running results (the title of the figure only shows cos(x) at this time)

If the code is modified to:

ezplot( 'sin(x)', [ 0, 2 * pi ] );hold onezplot( 'cos(x)', [ 0, 2 * pi ] );title( 'sin(x), cos(x)' );

There is an output:
