Hi Everybody, So basically I spent the summer working on some optics related stuff and now they want me to present my research work. This means I'm going to have to do numerical simulations for diffraction of Laguerre-Gaussian beam modes. In a word, the integrals are ridiculously long and complicated if they're integrable. Often my computer will be running a long time just to add an integral sign to my expression. Anyway the question is: When trying to calculations on a laptop (Macbook Pro, 13", 2.26 ghz processor and 4gb of RAM), which software is better to use: Mathematica or Maple. I'm more acquainted with mathematica but the problem with it is it'll take forever trying to calculate the integral before just putting an integral sign in front of my expression and then trying to plot the absolute value of the function (bc i want the intensity distribution) takes FOREVER. I've never used maple before but I can probably learn the basics quickly. So Maple or Mathematica or maybe just not use my laptop. Thanks!
