Skipping first few lines while loading text file
显示 更早的评论
I have a text file which looks like the one attached. How to skip first five lines and import the rest as a matrix. Thanks in advance for help

That file is a mess. It looks like the number of spaces around the numbers is significant, which is never a good idea.
Thankfully for you readmatrix seem to import the file correctly. It also detects the number of header lines on its own. All the importing functions (csvread, dlmread, readtable, readmatrix) allows you to specify the number of header lines if you need to. The last two can detect that automatically, so:
data = readmatrix('Full_beam-OAM_plate_l= 1_Intensity.txt')

Since you didn't put the version of matlab you are using in the field designed for that purpose (on the right of the web page), I assumed you were using a recent version. If you are using an old version before readmatrix was introduced, then yes you will get that error.
So we dont' waste our time giving you non-applicable answers: which version are you using?

Then the easiest is problaby:
data = table2array(readtable('Full_beam-OAM_plate_l= 1_Intensity.txt'))
