I hope someone can help me. I am using Maple 10 to make a model of some of my research on fruitfly dorsal-ventral formation. I am far from a math and maple expert, so i hope someone in here can help me. I have plottet my data with pointplot3d and need a function i can fit to to my data. Have tried with one time-frame at a time, using fit[leastsquares], but don't get a good result. Have a lot of "noise" on my measurements, that probably wont give a good result, I therefore need a full 3d fit. The data seen from (y,z)-axis is increasing "shark-fin" pattern: .............................................xxxxxxxxx .........................xxxx........xxx.......... ............xx.......xx....x......xx............. ...x....xx...x....x.......x....x................ xx.xx........xx..........xxxx................. , and decending negatively squared along the x-axis. Would like to post my results, but dont know if its possible, so if people want a crack at it, i have uploaded it, with my tries on it, at: http://www.megaupload.com/?d=JK70IPS5 Thank you to everybody who are willing just to have a look at it. (I posted this same subject before, but it was a bit premature. Sorry!)
