I used StarryNight back when I was still using Windows. Very nice app. Now on my Mac I use Stellarium which is also a very good app in my opinion. On my Galaxy Tab, Ipad, and Iphone I use Star Chart which I enjoy a lot

Thanks for the help. Does that mean that whenever I need *, /, ^, I need to enter a dot if it's not Matrix operations ?

Great, thanks for the help. This actually works and gives the same result as Mathematica. Can anyone tell me why those dot's need to be there ? Is there a rule or so about when to put a dot and where ? Regards, Michael

Hey everyone, I'm trying to create a plot in Matlab but just keep getting errors. It works very well in Mathematica but I want to learn some Matlab. However with all the errors I get I will probably stay with Mathematica. Maybe someone here can help me out. So, I'd like to create a plot of...

Hi, Thanks for the info. I've been looking around on Wolframs website and looked at a few examples. I just got the book "An Introduction to Programming with Mathematica". This one seems quite good in explaining things. I've done quite some calculations in Mathematica during the learning...

OK I found it myself. Instead of just writing -2^2, I have to write (-2)^2 and this gives the correct result. However, the question about a functional programming tutorial still stands. Michael

Hi, Quick question about Mathematica. As far as I know, squaring a negative number should give a positive result, right ? Let's say -2² should be 4 or is that wrong ? When doing this in Mathematica I get -4 as a result. Shouldn't it be 4 ? Any help is greatly appreciated. Also, does...

Thanks for the reply. Appreciated ! I'll take a look at 'Mathematica Cookbook'. I didn't expect to find a whole book on GUI programming. The main interest is in programming "applications" as can be found on Mathematicas website. We'll see if the Mathematica Cookbook will help.

Hi everybody, This is my first post in this forum. So, "Hello everybody" ! I hope someone can help me. I started to learn Mathematica a few weeks back and really like the software. I actually prefer it over Matlab but that's just my personal opinion. I used 'Mathematica demystified' and...
