Langmuir Nonlinear Model
Description
This model will fit the adsorption data to the nonlinear form of the Langmuir equation and will give the estimates of the Langmuir parameters, namely "b" and "k" while evaluating the performance efficiency of the nonlinear model of Langmuir through several error functions.
