  Dx = 1e-05,
  Eo = 0,
  Dm = 0.45,
  Vi = 0.3,
  Vf = -0.3,
  Vs = 0.001,
  ko = 0.01,

  n = 1,
  Area = 1,
  l = 100,
  DerApprox = 2,
  errCheck = FALSE,
  Method = "Euler"
)

Arguments

Co	bulk concentration expressed in Molar
Dx	diffusion coefficient expressed in cm^2/s
Eo	reduction potential of the species expressed in Volt
Dm	simulation parameter, maximum 0.5 for explicit methods
Vi	initial potential of the sweep expressed in Volt
Vf	final potential of the sweep expressed in Volt
Vs	potential scan rate of the simulation expressed in V/s
ko	heterogeneous electron transfer rate constant expressed in m/s
alpha	charge transfer coefficient
Temp	temperature in kelvin
n	number of electrons involved in the process
Area	area of the electrode expressed in cm^2
l	number of time steps of the simulation
DerApprox	number of point for the approximation of the first derivative
errCheck	if true the function returns a list with parameters for CottrCheck function
Method	method to be used for the simulation = "Euler" "BI" "RK4" "CN" "BDF"

Value

if errCheck == F a graph I vs E, if errCheck == T a list

Examples
