In spite of going through Matlab help and several attempts, I still do not get how to use "textscan" or other relevant functions to read from a simple non-rectangular file like the attached sample.
All I want is to efficiently extract two integers from the first line and two cell arrays (or char arrays) each containing the strings respectively to the left and two the right of | in the subsequent lines. Here is the code I tried, but it does not work:
fid = fopen('dataset.txt');
coeffs = textscan(fid, '%s%s', 1, 'Delimiter', ' ');
sequences = textscan(fid, '%s%s', 'Delimiter', '|');
Using "fileread" and "regexp" also seem to be options, but "regexp" seems slower than "textscan".
BTW if anybody can point me to a link where I can find how to extract data from files using Matlab, with examples providing ample coverage of use cases, that would be great.
