Hello acer,

thank you for you quick reply.

I think the conversion between matlab and maple is not the problem since matlab allows you to directly access the maple kernel and thus you can see what is calculated there.

It would be great if you could confirm my result with maple though!

Of course I can give you the function:

-3/532*pi*(11881-2500*ne^2)^(1/2)+1/2*atan(((ne^2-841/400)/(11881/2500-ne^2))^(1/2))+1/2*atan(((ne^2-1)/(11881/2500-ne^2))^(1/2))+1/2*conj(-3/266*pi*(11881-2500*ne^2)^(1/2)+atan(((ne^2-841/400)/(11881/2500-ne^2))^(1/2))+atan(((ne^2-1)/(11881/2500-ne^2))^(1/2)))=0

where ne is the quantity I need.

With matlab and "solve" I receive:

ans =

-1.9091740680953580279920587820837

The same goes for accessing maples fsolve and the startingvalue -1 for example.

The value I need is +1.909... however. I get the correct result for fsolve and x0 = 1.9. Nevertheless it would be perfect to get all results from solve.

Regards

Kalle

I forgot to tell you that I work with Matlab and the symbolic math toolbox which allows one to access the maple kernel.

I'm afraid, the maple help is not includes into this toolbox, so is there a possibility to see the maple help without having the actual programm, because there is the promising line "  For detailed information including:

- Complete description of all parameters

- Complete description of functionality

- Complete description of output

- Shortcuts for specifying equations and unknowns

- Controlling the form and number of solutions returned

  see the ?solve/details (solve,details) help page."
