Generating a ground structure with geometrically orthotropic symmetry for topology optimization
Please cite the following paper when using these Matlab scripts:

Example:
[barNode,nodeCoor,nDesVar] = GenerateGS(5,5,5);
designVar=zeros(1,405); designVar(300)=1;
isActive = ActiveBar(barNode,nodeCoor,nDesVar,designVar);
