I'm trying to import data from a text file into matlab. The data consists of various numbers in this form: 1,2,3,4,5,6,7 and has may different rows but some rows have random text. I tried using load but that won't work because of the random text and different sized data. How can i import the data and remove the text? example of how the text file is layed out:
