How to loop through a folder of ifiles in Matlab

Hello all,

I have a lack of efficiency of my script that it could be sort out whether I were able to loop through a folder where I have all my files.

The script is working fine the only thing is that I have to go file by file loading them. I have searched for information of how to do it and most of it explain how to get txt. .cvs. jpg and so on. However, I have a bunch of Ifiles coming from AVL combustion system, which I am not sure how to load them one by one in a loop.

The idea it would to run a loop where you can load each ifile in a function to extract all the variables only selecting the folder. I have managed to have everything working but I am stack in that step. In this way, I could leave the script overnight working rather than the need to go one by one.

Any help it would be more than welcome.

Thank you very much.

File format?

I Have No Idea What Is This ifile format. But This File Exchange Seems Exactly Like What You're Looking For:

Hello,

Thank you for the answer, that is the File exhange I am using to get the data from this Ifiles to extract my data. This files are used by engines combustions analyser softwares. The thing is that I can only load a file at the time as I introduce manually the name of the file. However, I have more than 100 files, so it is quite time consuming.

I will try to work and try to find a way.

thanks for your help

Ok, so you only need to iterate through your files?

I think this should do the it:

path = pwd; % set your folder path here
filePattern = '*.ifile'; % or whatever file extension these files are saved as
files = dir([path '\' filePattern]);
fileNames = strcat({files.folder}, '\', {files.name});

% I think that load_ifile returns a struct?
% If you know in advance what fields it has, and all structs have the same
% fields, you can use a struct array instead of a cell array
data = cell(1, length(files));
for i = 1:length(files)
    data{i} = load_ifile(fileNames{i});
end

Hi,

yes, I just need to iterate through the files and you are correct, it is a struct and it a good point about to use struct array instead of cell array.I will try what you suggested me tomorrow at work and let you know!!!

thanks for your help.

best regards!!
