exp2

mdhelper.fit.exponential.exp2(x: ndarray, a: float, b: float, c: float, d: float) → ndarray

Convenience function for the exp2 model from MATLAB.

\[y=a\exp{(bx)}+c\exp{(dx)}\]

Parameters:

xnumpy.ndarray

One-dimensional array containing \(x\)-values.

afloat

Coefficient \(a\) for the first \(\exp\) term.

bfloat

Coefficient \(b\) for the \(x\) term in the first \(\exp\) term.

cfloat

Coefficient \(a\) for the second \(\exp\) term.

dfloat

Coefficient \(b\) for the \(x\) term in the second \(\exp\) term.

Returns:

fitnumpy.ndarray

Fitted \(y\)-values.
