Hello
I have a text file containing special characters, text and some numbers and I need to extract from it some values which appear every n-th row. Since the file has around 20k rows, I want the algorithm to find first and next rows. I've read text file to matrix with readdlm(), but the type of array is ANY, and findfirst() gives and error "access to undefined reference". Could you give me some guidance, please? Regards Mike
