catool can be used to convert raw combustion data in AVL IFile format for later analysis in The MathWorks' MATLAB or GNU Octave.
Step-by-step:
1) Create a directory to store the catool files such as 'C:\Users\Your Username\Documents\MATLAB\catool'.
2) Copy the load_ifile.m script to the above directory.
3) Add the above path: (at MATLAB prompt) addpath('C:\Users\Your Username\Documents\MATLAB\catool')
4) Load the data: (at MATLAB prompt) ifile = load_ifile('avl_ifile.001')
5) Plot the data: (at MATLAB prompt) plot(ifile.CYLPR1.axis,ifile.CYLPR1.data)
