RHLightResponseCostC

Computing residual sum of squares for predictions vs. data of NEE implemented in C. See LightResponseCurveFitter_computeCost for a description.

RHLightResponseCostC(theta, flux, sdFlux,
    parameterPrior, sdParameterPrior, Rg,
    VPD, Temp, VPD0, fixVPD)

Arguments

theta

parameter vector with positions as in argument of LightResponseCurveFitter_getParameterNames

flux

numeric: NEP (-NEE) or GPP time series [umolCO2 / m2 / s], should not contain NA

sdFlux

numeric: standard deviation of Flux [umolCO2 / m2 / s], should not contain NA

parameterPrior

numeric vector along theta: prior estimate of parameter (range of values)

sdParameterPrior

standard deviation of parameterPrior

Rg

ppfd [numeric] -> photosynthetic flux density [umol / m2 / s] or Global Radiation

VPD

VPD [numeric] -> Vapor Pressure Deficit [hPa]

Temp

Temp [degC] -> Temperature [degC]

VPD0

VPD0 [hPa] -> Parameters VPD0 fixed to 10 hPa

fixVPD

boolean scalar or vector of nrow theta: fixVPD if TRUE the VPD effect is not considered and VPD is not part of the computation
