deriv_ma: Calculates derivatives of mass-action kinetics.

In cdiener/dycone: dycone - analyze the dynamic landscape of metabolome data

Description

deriv_ma does not check whether the ordering of substrates in the stoichiometry and concs is corrects, so please make sure that the indices in substrates and concs coincide.

Usage

deriv_ma(i, substrates, concs)

Arguments

i	The index of the substrate used as the differentiation variable.
substrates	The stoichiometry of the subbstrates (column in the stochiometric matrix. Must be the same length as concs.
concs	Concentrations of the substrates.

Value

Returns the derivative of the mass action kinetics for the reaction specified by subtrates differentiated by the ith variable.

See Also

jacobian to calculate the Jacobian matrix.

Examples

data(eryth)
S <- stoichiometry(eryth)
dma1_dS3 <- deriv_ma(3, S[,1], runif(nrow(S)))
