Ok, I just download it and ran a series of tests with a variety of input parameters. Everything look fine to me. I get in return the point set V, the triangulation T, and the display when I whish. Could you please check again your code, and especially also you have not modified the files ? Could you download and try again ? Thank you.
Hi 风小子 zeng, Thabk you for this report. Could you copy and paste your piece of code in comments -or send it to me by pm- for me to reproduce and solve this error ? Thank you. Best. Nicolas

Matrix dimensions must agree.
Error in Spherpinski (line 167)
V1 = V1./D1;
A set of functions to compute a Sierpinski sphere (fractal 3D surface) with some options (nb_iterations, option_fill, option_display). The resulting sets of vertices and triangles are also available for further computations.
The algorithm principle is based on the projection of the Sierpinski triangular faces of a regular octahedron on the surface of the unitary sphere.
NB : function sample_triangle is included, but may also be found independently here :

Tip : from nb_iterations = 4, and if using write_ply.m you struggle with displaying the set out of Matlab [...] try to replace in the file header "uchar ushort" by "uint8 uint32" this may help ;-)
