matlab函数linspace参数过多（matlab 函数参数）



matlab画三维函数参数⽅程,如何在matlab中绘制含有三个参

数⽅程的三维图形

【1】ezimplot3 存储该M⽂件，并将⽂件路径设置为matlab当前路径

function h = ezimplot3(fun,domain,n,color)

% EZIMPLOT3 Easy to use 3D implicit plotter.

% EZIMPLOT3(FUN) plots the inline function FUN(X,Y,Z) = 0 over the

% default domain -2*PI X 2*PI, -2*PI Y 2*PI, -2*PI Z 2*PI.

%

% EZIMPLOT3(FUN,DOMAIN)plots FUN over the specified DOMAIN instead of the

% default domain. DOMAIN can be the vector [XMIN,XMAX,YMIN,YMAX,ZMIN,ZMAX]

% or the vector [A,B] (to plot over A X B, A Y B, A Z B).

%

% EZIMPLOT3(...,N) plots FUN over the default domain using an N-by-N grid.

% The default value for N is 60.

%

% Example

% Plot x^3+exp(y)-cosh(z)=4

%

% via a string: f=x^3+exp(y)-cosh(z)-4

% ezimplot3(f)

%

% via a vectorized function handle: f = @(x,y,z) x.^3+exp(y)-cosh(z)-4

% ezimplot3(f)

%

% Note: this function do not use the ezgraph3 standard, like ezsurf, ezmesh

% ,etc, does. Because of that, ezimplot3 only tries to imitate that

% interface. A future work must be to modify the ezgraph3 to include a

% routine for implicit surfaces based on this file

%

% Inspired by works of: A.Jutan UWO 02-02-98

% Made by: G.Morales UC 03-20-09

%

if nargin == 1

domain = [-2*pi, 2*pi]; % default domain: -2*pi xi 2*pi

n = 60; % default grid size

elseif nargin == 2

n = 60; % just default grid

end

if size(domain,2) == 2

domain = repmat(domain,1,3); %domain repeated in all variables

end

xm = linspace(domain(1), domain(2), n); % generating the volume data

ym = linspace(domain(3), domain(4), n);

zm = linspace(domain(5), domain(6), n);

[x,y,z] = meshgrid(xm, ym, zm);

if ischar(fun)

fun = inline(vectorize(fun)); % making sure string fun is vectorized

fvalues = feval(fun,x,y,z); % evaluating fun in domain

elseif isa(f
