Hi together,
i do need to calculate an exponential fit to my data to finally get out the lamda. In matlab, this is no problem since I can use the 'fit'-option. I tried some possibilities (e.g. expfit), but I failed :-(
maybe some of you can help me:
I have two columns of data, e.g:
| x |
y |
| 18 |
20 |
| 16 |
30 |
| 13 |
40 |
| 11 |
60 |
| 9 |
80 |
| 7 |
100 |
| 5 |
150 |
| 3 |
220 |
How can I calculate a fit according a general exp model according to
f(x) = a*exp(b*x)
... I need the calculated b for this curve...
I hope sombody can help me with this!
Thnaks a lot and best regards,
Tom
