Physicia contains 17 independent modules under top directory. Physica is portable, therefore it does not need any installation process. How to use 1. Unzip the Physicia_vXXX.zip. 2. Open physicia/physicia.m with MATLAB, and run the script with "Changing folder". 3. If you want to directly run a specific module, move to the corresponding subfolder and run the script. The modules in the Physicia directory are basically independent, but some modules have dependency on physicia/CommonFunction folder. If you want to extract a specific module, it is recommended to locate physica/CommonFunction folder together. PHYSICIA V2.00, Copyright ⓒ Department of Physics at POSTECH in Korea.
