Deleting Some initials of The Matrix

I have data as given in the above picture.I want to delete the selected part ( Bluish part in the picture) and consider all other matrix (excluding that bluish part),for my analysis. Is there any way of doing it??Because I have 100s of these types of text files and I can't delete this part ( bluish part in the picture) by going to each indivdual text file one by one.Any help will be really appreciated because It will save alot of hardwork and time.

Thank You

It depends on the functions you have available. It appears to be a text file, so one option would be textscan:

fidi = fopen('YourFile.txt,'rt');
Datac = textscan(fidi, '%f%f%f%f', 'HeaderLines',9, 'CollectOutput',1);
Data = cell2mat(Datac);

Likely the best option otherwise would be readmatrix, introduced in R2019a.
