Re: Simulations
Solve the equation
for x. You get 2 solutions:
I used the second one.

Re: Simulations
Hi,
Hope you don't mind replying to old ones, I'll post code whichever I'll be able to come up with!
J:
samp=:1000000
f=:1+?samp$0
fx=:2*(1-%f^2)
(+/%#)f*fx≈1.61407

Hi gAr;
You can post it and thanks for doing so.

Re: Simulations
Okay, it's very lightweight when compared to other functional programming languages, so I'm fascinated!

Hi;
It is light in m too.

Re: Simulations
Hi,
I meant the size of the whole package..

Oh sorry, I did not understand. I thought you meant program size.

Re: Simulations
No problem, i'll explore more into the functional stuff..

Re: Simulations
I prefer it too but I am afraid that it will always be like a second language to me. When you begin with procedural you are poisoned for life. See you later, got to get off.

Re: Simulations
myPDF[]=ProbabilityDistribution[2(1-1/x^2),{x,1,2}];
Is that an array construct?

Re: Simulations
No, that is a PDF. The random variate command constructs an array of random numbers that obey that PDF.

Re: Simulations
How about writing a CFD simulation or a chemistry one?

How does that relate to Computer math?
