range_tau: Bounds of tau

Description

Computes the bounds of the driving variable (or position) \(\tau\) on the straight line of relative concentrations such as thereof are between 0 and 1

Usage

range_tau(E_ini_fun,B_fun)

Arguments

E_ini_fun

Numeric vector of initial concentrations

B_fun

Numeric vector of global co-regulation coefficients. Same length as E_ini_fun.

Value

Numeric vector of the inferior and the superior bounds of driving variable \(\tau\)

Details

Relative concentrations is defined in [0,1]. This function range_tau computes the bounds of \(\tau\) such as all relative concentrations are between 0 and 1.

The inferior (resp. superior) bound of \(\tau\) corresponds to minimal (resp. maximal) value of \(\tau\) such as all relative concentrations are superior or equal to 0 and inferior or equal to 1, with at least one relative concentration equal to 0 or 1.

Examples

# NOT RUN {
beta <- matrix(c(1,10,5,0.1,1,0.5,0.2,2,1),nrow=3)
B <- apply(beta,1,sumbis)
E0 <- c(30,30,30)

range_tau(E0,B)
