How to cut ASCII file with matlab ?

Hy everyone,

I need help.

I'm trying to post process some ASCII files from fluent.

The problem is that I extract several lines from differents sizes (number of cells) and they are put together in the ASCII file.

I would like to cut the files for each lines automatically and I don't konw how ...

Finally i'm trying to create un .mat file with all the data to be able to plot some values.

For now I'm doing it manually (see the code)

clear all

close all

Thank's for your help !!

[KSSV]

You need to attach your file and show us what you want to read.

[Mathieu TOCQUER]

Thank you.

I attach the file to the topic.

Answer 1

[Mathieu NOE]

hello Mathieu

this would be my suggestion - create a structure with field names taken from your data file -

See the function file in attachment also - an older wrapper to get headers and numeric content from mixed txt files - still helpfull even though modern matlab releases offer more options - someone will probably prefer a

readtable

code instead.

So my suggestion

[outdata,head] = readclm('data_ligne_100k_3mm.txt'); % or use equivalent function (readtable and alike)
[m,n] = size(outdata);

data_names = split(head);
emptyCells = cellfun('isempty', data_names); 
data_names(emptyCells) = []; % remove empty names from list

% find lines matching "1" in the first column (as data block separator)
ind = find(outdata(:,1) < 1.1);
ind = [ind;m+1]; % add end of line index +1

% grouping all these variables under an overarching struct
 Content = struct() ;
 for ck = 1 : numel(data_names)
     fn = data_names{ck};
     fn = strrep(fn,'-','_'); % - is not allowed in field names , replaced by _
     
     for cj = 1:numel(ind)-1
         start = ind(cj);
         stop = ind(cj+1)-1;
         str = ['_' num2str(cj-1) 'h'];
         fnn = [fn str];
        Content.(fnn) = outdata(start:stop,ck);
     end
    
 end

will create a structure Content with your data as requested :

Content = struct with fields:
