CalcGamma() computes a 1-D, 2-D, or 3-D local or global Gamma index between two datasets (reference and target) given a defined coordinate space using MATLAB. The Gamma analysis is performed based on the formalism presented by D. A. Low et. al., A technique for the quantitative evaluation of dose distributions., Med Phys. 1998 May; 25(5): 656-61.
