How can I load coded ascii files?

My files are '-P01' and seem to have non-rectangular matrix formats. They contain text and number data points. Here is the list of a few commands I've used without success, as well as the error descriptions.

>> load('CA10.Cyl1.P01')
Error using load
Unknown text on line number 2 of ASCII file CA10.Cyl1.P01
"".

>> load('CA10.Cyl1.P01','-mat')
Error using load
Unable to read MAT-file D:\Backup\LD Consortium\VVA on CLO\ESN01\20180605_Lamb\CAS\3\CA10.Cyl1.P01. File might be
corrupt.

>> importdata('CA10.Cyl1.P01')

ans = 

      ''
      '   2          '
      '   CA10.Cyl1001 +‡v?P½P½+‡v?j¼„¿/¡À/À/À/ÀP½5^BÀåО@j¼„¿/À5^À5^Àj¼„¿5^ÀP½Ë¡=@5^BÀ5^À+‡v...'

I've tried multiple other commands with no luck. Any information would be much appreciated. I cannot include the file because the extension isn't in a valid attachment format.

You can include it inside a zip. But the more important question is: what is the file definition? Why do you expect Matlab to know this file type?

You can read it with fread and process it yourself if you know what the file format is.

Are those archives created with QuickPar ?

@Rik,

The problem is I do not know the file definition. The recording software manual is very vague. These files were produced with A&D Technology software.

With certain file names (I assume the ones without comments in the first few lines of the file,) I can specify a '-mat' extension and they load correctly. I've attached a zip folder with the file that will not load as well as 'tqca0.P01' which does load correctly with the '-mat' extension specification.

The software does allow for a -mat conversion after logging, except it saves the file names with invalid characters which do not load correctly. I've also included 'Knock Pk-Pk.AVL.mat' which is a sample of the files with incorrect naming. If there is a way to get this file to load I would not necessarily need the '-P01' files, but ideally the '-P01' file would be best because I've had issues with the software freezing in the past during the '-mat' conversion process.

Thank you for your time, Joel

@Walter,

These were created with A&D Tech's CAS system.

See https://www.mathworks.com/matlabcentral/fileexchange/42274-loadfixnames-loads-a-mat-file--fixing-invalid-names for software that can read the .mat files.

I notice that https://sites.ualberta.ca/~ckoch/Thesis/MMthesis_20120608.pdf mentions having software to convert P01 files to .mat
