REad about textscan; here you can provide the number of header lines.

Answer 2

[Kojiro Saito]

I'm not sure about your MATLAB version, but from R2016b, you can use delimitedTextImportOptions which can be called with detectImportOptions.

I assume You have a text file in which top 33 lines are header and line 34 is a column name, so the following will work.

opts = detectImportOptions('your.txt', 'NumHeaderLines', 33);
t = readtable('test.txt', opts);

Then, you can get 12x16 table.
