This file refers to scripts in the zip archive: www.perplex.ethz.ch/perplex/ibm_and_mac_archives/Perple_X_Compiled_MatLab_scripts.zip This archive contains compiled versions of various Perple_X MatLab plotting scripts that can be used without purchasing MatLab. However, if you do not have MatLab installed on your computer you must download and install the free "MatLab Compiler Runtime (MCR)" as described in "readme_what_you_need_to_download.txt" file that is located in the folder corresponding to your operating system. The disadvantage of using compiled MatLab scripts is that you cannot customize the functionality of the scripts. The MatLab scripts included in this archive demonstrate how 2 and 3D data generated by the Perple_X programs WERAMI, FRENDLY and FLUIDS can be manipulated or plotted in MatLab. The compiled scripts are: perple_x_plot.exe - plots 2/3D data images. perple_x_plot_ratio_of_data_in_2_files.exe - plots the ratio of 3D data stored in two different files. perple_x_extract_o_bat.exe - a program to extract the X-Y coordinates of an X-Y-Z contour, e.g., an adiabatic or isochoric path as a function of pressure and temperature.
