Question

x²+y²-z²=1，用matlab画图，写出程序语言。不用附图。

Answer 1

你可以使用isosurface来提取等值面，

[x,y,z] = meshgrid( linspace( -10, 10, 100 ) );
f = x.^2 + y.^2 - z.^2 ;
isosurface(x, y, z, f, 1);
grid on

Answer 2

[x,y,z] = meshgrid( linspace( -10, 10, 100 ) );
f = x.^2 + y.^2 - z.^2 ;
isosurface(x, y, z, f, 1);
grid on

Answer 3

[x,y,z] = meshgrid( linspace( -10, 10, 100 ) );
f = x.^2 + y.^2 - z.^2 ;
isosurface(x, y, z, f, 1);
grid on
