Julia Update

Posted on the 16 September 2014 by Ccc1685 @ccc1685

I’m totally committed to Julia now.  It is blitzing fast and very similar to Matlab with some small differences (improvements). I particularly like the fact that when you declare an array with one argument, like x = zeros(10), it immediately gives you a vector of length 10 and not a 10 X 10 matrix. The broadcast function is also very useful.  There are still many things I don’t yet know how to do in Julia like how to import and export data.  Plotting is also not fully solved. I’ve been using PyCall to import matplotlib.pyplot, which works pretty well but not perfectly. There are things I miss in Matlab like context dependent history recall, i.e. I can recall an old command line by just typing the first few letters.  If anyone knows how to do this in Julia please let me know.  Right now, I’m hitting the uparrow button continuously until I find the line I want. I do worry that my abandoning Matlab means someone will lose their job, which is certainly not my intention. However, I am well ahead of schedule for zero Matlab.
