In waveformlidar: Waveform LiDAR Data Processing and Analysis

Description Usage Arguments Value Examples

The function allows you to prepare the formula and start values for adaptive or generalized Gaussian decomposition using nlsLM.

1	agennls(A, u, sig, r)

`A`	is the amplitude of waveform.
`u`	is the peak location of waveform.
`sig`	is the echo width of waveform.
`r`	is the rate parameter of adpative or generalized Gaussian distribution. For Gaussian distributionm, r is fixed to 2.

return a formula suitable for different number of waveform componments with adaptive Gaussian distribution.
