I am reading data from a file into mathematica. It is too much to be stored in a mathematica file. I want to do all of my calculations in mathematica but I want the data to be an array of a table. How do I put my data into a table so that a table with a nested loop like
For [j=0, j<20, j++
also, I want it to read until the end of a file- for a length I am not sure of. How do you do that too?
