Description
The method calculates sensitivities associated with the steady state of the purely temporal system
where c is the n-vector of species concentrations, α is the m-vector of systems parameters (which can include the initial conditions c0), and t (time) is the variable of integration.
The local sensitivities ∂c/∂αj are calculated via finite difference approximations
where css(αj) and css(αj+Δαj) correspond to the solutions of the algebraic systems f(c, αj) = 0 and f(c, αj+Δαj) = 0 respectively.
