- FitExp[ <List of Points> ]
- Calculates the exponential regression curve in the form e ^ { a x }
- Example:
FitExp[{(0, 1), (2, 4)}]yields e^{0.69 x}.
Note:
- If you want the answer in the form a x ^ b then use the FitGrowth Command
- Euler's number ℯ can be obtained by pressing ALT + e.
- See also FitLog Command, FitPoly Command, FitPow Command and FitSin Command.
CAS Syntax
- FitExp[ <List of Points> ]
