Matlab makes the intersection of space curve

Transfer from http://www.ilovematlab.cn/thread-168239-1-1.html

Bloggers are learning triple points recently, unfortunately the ability to imagine the space is really catching up, had to resort to Matlab.

Online provides a very good program, the line is very clear, really help me a lot.

Post the program:

Clear ALLCLC; [x, Y] = Meshgrid ( -2:0.1:2), Z1 = X.^2-2*Y.^2;Z2 = X.^2+y.^2-5;mesh (X,Y,Z1); hold On;mesh (X,Y,Z2); r0 = (ABS (Z1-Z2) <=0.1 ); zz = R0.*z1;yy = R0.*y;xx = R0.*x;plot3 (xx (r0~=0), yy (r0~=0), ZZ (r0~=0), '-k* '), ColorMap (cool) hold off

　　

The time to modify Meshgrid and Z1 Z2 can be, put out a sheet.
