load_ifile(filename​,offset_correction)

Allows MATLAB to load internal combustion engine pressure data stored in the AVL I-File format

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)
