triple numerical integration

HI
I need any information or book about (triple numerical integration)

:(

bobbym · 2014-03-23 05:22:56

Numerical integration for more than one dimension is more difficult. Do you have a problem to show?

ammar · 2014-03-23 05:30:46

No I need at least one example , I don't have any information about it

bobbym · 2014-03-23 05:45:16

I will try to get one for you. It will take some time.

Formula 2.9 shows in a difficult way how to derive the trapezoidal rule for a triple integral.

There is also Monte Carlo integration which is sometimes used.

OK thanks I'll try with this

Hi;

Keep in mind that these are closer to algorithmic techniques and as such are best done by computers.

There are many problems associated with using formulas for numerical cubature as it is called. For one thing, the convergence can be very slow and the function evaluations costly.

Let me know how you do.

I need example to verify this formula and I'll try to solve it by matlab and by steps

bobbym · 2014-03-24 03:27:23

Hi;

Can I see your formula?

ammar · 2014-03-24 03:59:57

I mean the formula 2.9 , in triple I don't know how I deal with slice of dz ,

I think we try the inside double integration at each slice of dz

bobbym · 2014-03-24 04:05:05

Maybe it would be easier to use Monte Carlo on a triple?

ammar · 2014-03-24 04:19:35

Please if you find an example about triple numerical ,I'll use matlab it's easier

bobbym · 2014-03-24 04:25:13

There are matlab commands to do it.

ammar · 2014-03-31 03:32:39

HI again ,
Can you find triple numerical integration by surface not by line ?

I searched about it but I don't know the method of the subject

bobbym · 2014-03-31 03:44:19

I do not know the answer to that.

If you know how to use Matlab on it then try this example:

It is easy to do analytically and will make a good test for you.
