Is this really supposed to do anything, other than calculating 9,000,000 times the same thing, i.e., Sin (45.0)*ArcSin (0.5)*Sqrt (5.0)*ArcTan (2.5555), a task which takes 46 seconds in my PC (using the right syntax)? To obtain x in a very short time you just have to calculate it only once... -Tomas > Date: Tue, 21 Feb 2012 06:09:34 -0500 > From: gearss8888 at gmail.com > Subject: How I can I optimize the following code in order to get very short running time > To: mathgroup at smc.vnet.net > > How I can I optimize the following code in order to get very short > running time? > > Time1 = AbsoluteTime[]; > n = 3000; > Do[Do[x = > Sin (45.0)*ArcSin (0.5)*Sqrt (5.0)*ArcTan (2.5555);, {n}], {n}]; > Time2 = AbsoluteTime[]; > Print[Time2 - Time1]; >
