Hi, Thank you my friend. Yes your worksheet is correct and the results are the same which must be.

I run my Maple's program on laptop on 64-bit, Win8. I was wondering if the different versions of Maple have different performances on different systems?(For example on Win 7, or Win8...)

Regards.

Hi, I thank you a lot if you send me the file which you ran in your computer, I can use it.

Hi, my Maple's version is 17. But I think my Maple doesn't work correctly and you're right. Please send me your worksheet in which all 14 roots found by NextZero have residuals less than 5*10^(-Digits). I wrote  guardDigits= 22, because for another values of it, the number of roots were less...

Could you send me your Maple software? Ofcourse it has 2 Gb!!! 

I'm studying Fluid Mechanics and I don't have enough science about these special function, Heun, Kummer...

Hi  all.

I thank you for your responses. I checked the roots which were found from two methods: by   fsolve  and by RootFinding:-NextZero. I think  whole of these roots aren't true, please take a look at the attached file.

Hi friend, excuse me for the fault I did...

Why when I run your code in my laptop ( Maple 17), it doesn't work as yours?
