Step discrete function u[k]
I need to define my symbolic discrete function only for k>=2. In the paper i write something like f(k)=2^k * u (k-2) u(k) is a step discrete function that is 0 for k<0 and 1 for k>=0. So u(k-2) is 0 for k<2 and 1 for k>=2. (The purpose is to CUTOFF a part of function). Ok I just need this on matlab. I tryed: ... 25 Jun 2010 15:22

using textread to read in data to a 2D array
I have data files that are: 34 columns a heck of a lot of rows! I need to read in the data (skipping the first 14 lines of header) to an array. I do have a way to do this, but I have found that it slows down on my large files. What I've done and it works, is: temp = textread(filename, '%f', 'headerlines',... 25 Jun 2010 16:28
