| Dec 7, 2012 at 22:34 | comment | added | mia | thank you Simon & Mr.Wizard! mia is happy to return to her old identity :) | |
| Dec 7, 2012 at 22:15 | comment | added | Mr.Wizard | @mia It should now be fixed. | |
| Dec 7, 2012 at 22:06 | comment | added | Simon | @mia: As you earn more reputation, you can do more in the site. Also, it looks like you've opened up two different accounts. I'll flag this to get fixed for you. | |
| Dec 7, 2012 at 21:52 | comment | added | mia | it seems that I can add comments only to my 'answer', the one that I started here, otherwise I can only give feedback to a particular answer (as I said I have no idea what happened with the account I did this morning, but I cannot login anymore) -- this is probably very confusing :-) | |
| Dec 7, 2012 at 21:50 | comment | added | mia | yes, it does satisfy the equation :). Now I need to replace the kernel with the 'real thing' (the real physical interaction), hopefully it will work as well. | |
| Dec 7, 2012 at 21:48 | comment | added | mia | Thank you for the tips, I would be very happy if there is anything I can help with. | |
| Dec 7, 2012 at 21:45 | comment | added | chris | Did you check that the solution actually satisfies the integral equation? I am failing to verify this but may be I am getting tired :-) | |

well if you like my answer you can 1) As you receive help, try to give it too, by answering questions in your area of expertise. 2)Read the FAQs! 3) When you see good Q&A, vote them up by clicking the gray triangles, because the credibility of the system is based on the reputation gained by users sharing their knowledge. ALSO, remember to accept the answer, if any, that solves your problem, by clicking the checkmark sign

| Dec 7, 2012 at 21:40 | comment | added | mia | Chris, I know this is not the right place to say thank you, but apparently mia is not able to post anymore (no idea why), so I am just going to say that your code works just beautifully! I had spotted a couple of things that needed to be corrected, but you did it before I have noticed the possibility of editing somebody else's answer :). Thank you! ps. this is another mia, I just opened another account -- for unknown reasons the old mia is not able to write comments anymore :) | |

| Dec 7, 2012 at 19:40 | comment | added | chris | Note that I was a bit optimistic to assume that the approximate solution (the sum of BSplines) was exactly in the NullSpace of Q-M. Now I just look to the closest null solution. | |

| Dec 7, 2012 at 18:09 | comment | added | mia | I have also corrected some bugs in your code, still doesn't do, but I am very tired so maybe I just don't see things. Please let me know if you notice anything and again, thank you for taking so much time... | |
| Dec 7, 2012 at 14:53 | comment | added | mia | Sorry for annoying you again, but it seems to be a problem with the null space, which is always empty regardless of the kernel (I have tried several). Do you know what is happening? | |

| Dec 7, 2012 at 11:08 | comment | added | mia | Thank you so much Chris! I am trying to continue along your idea but I am quite slow -- mathematica is not really my forte, I have resorted to it after having failed in fortran :(. It is very frustrating, as I am stuck in this equation since a while now... Again, thank you so very much for your help, I hope I will manage to get it done... | |
