hess_exp_conv_gau¶
- TRXASprefitpack.mathfun.hess_exp_conv_gau(t: float | ndarray, fwhm: float, k: float) ndarray[source]¶
Compute hessian of exponential function convolved with normalized gaussian distribution
- Parameters:
t – time
fwhm – full width at half maximum of gaussian distribution
k – rate constant (inverse of life time)
- Returns:
Hessian of Convolution of normalized gaussian distribution and exponential decay \((\exp(-kt))\).
