How to read/load text file without header?

Hello,

I have a text file (attached here) which contains headers. How can I read/load just numeric data from the text file? In the attached file, for example, how can I get all data for column wav1-1 or wav1-2, etc?

Thank you!

readtable seems to work well on this file.

t = readtable('Test Data.txt');

Warning: Column headers from the file were modified to make them valid MATLAB identifiers before creating variable names for the table. The original column headers are saved in the VariableDescriptions property.
Set 'VariableNamingRule' to 'preserve' to use the original column headers as table variable names.

head(t) % check the first 10 rows -> looks ok
