Converting AVL IFile data to MATLAB

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:\Program Files\MATLAB\Rnnnn\toolbox\catool'. When Rnnnn is the MATLAB version, for example R2007b.

2) Extract the files from the 32 or 64 bit version of catool and load_ifile.m script to the above toolbox directory.

3) Add the above path: (at MATLAB prompt) addpath('C:\Program Files\MATLAB\Rnnnn\toolbox\catool')

4) Save the path: (at MATLAB prompt) savepath

5) Load the data: (at MATLAB prompt) ifile = load_ifile('avl_ifile.001',1)

6) Plot the data: (at MATLAB prompt) plot(ifile.CYLPR1.axis,ifile.CYLPR1.data)
