Dear All,

I need to read strings from a txt file which contains numerical data and strings. The file content is as follows:

model = [
1.23  45.6  789.0  abc
234.0  56.7  8.91  def
345.0  678.0  9.12  ghi
];

How can I read the strings and save them in a file called NameList?

Thanks in advance.

Benson

The text file, model.txt, contains the five lines given in your question.

The script

    fid = fopen( 'model.txt' );
    cac = textscan( fid, '%f%f%f%s', 'Headerlines',1        ...
                ,   'CommentStyle',']', 'CollectOutput', true );
    fclose( fid );

reads that file. Inspect the output

>> cac{:}
ans =
         1.23         45.6          789
          234         56.7         8.91
          345          678         9.12
ans =
  3×1 cell array
    {'abc'}
    {'def'}
    {'ghi'}
