This reposity implements a new verstion of the GJK algorithm to compute the minimum ditance between two convex bodies in 3D. All it needs are the coordinates of the bodies in [N x 3] matrices, where N is the number of points defining a body.

An example is provided in example2_mex/runme.m. By running this file, Matlab will compile a MEX funciton which is called thereaftert. To compile a MEX function you'll need a C/C++ compiler, please refer to Matlab documention or leave a comment below.

Thanks to Kwanyuan Chan for this tip to Windows users: Matlab users need to set up the MinGW-w64 C/C++ compiler before running the example2_mex/runme.m file. More about the compile and related setting procedures at:https://www.mathworks.com/matlabcentral/fileexchange/52848-matlab-support-for-mingw-w64-c-c-compiler
