You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: loadWashElutionSMAsystem.m
    path of file: ./repos/CADET/src/cadet-mi/examples/forward
    
    the code of the file until where you have to start completion: function [result, solution] = loadWashElutionSMAsystem()
%LOADWASHELUTIONSMASYSTEM Simple Load-Wash-Elution cycle with 4 component SMA model
%
%   The model is taken from the publication:
%   Püttmann, A.; Schnittert, S.; Naumann, U.; von Lieres, E. (2013). 
%   Fast and accurate parameter sensitivities for the general rate model 
%   of column liquid chromatography. Computers & Chemical Engineering, 56, 46–57. 
%   doi:10.1016/j.compchemeng.2013.04.021
%   
%   It describes ion-exchange chromatography of lysozyme, cytochrome and ribonuclease 
%   on the strong cation-exchanger SP Sepharose FF. The column is first loaded for 10s 
%   with a constant ionic strength of 50 mol / m^3 and lysozyme, cytochrome and ribonuclease

%   with a constant ionic strength of 50 mol / m^3 and lysozyme, cytochrome and ribonuclease 
%   concentrations of 1 mol / m^3. The column is then washed for 80s at the same ionic 
%   strength without proteins. The bound proteins are then eluted with a salt gradient from 
%   T = 90s to T = 1500s, starting at 100 mol / m^3 and with a slope of 0.2 mol / (m^3 * s). 
%
%   In this function, a ModelSystem consisting of inlet, general rate model, and outlet unit 
%   operations is constructed explicitly. See loadWashElutionSMAsingle() for a shorter
%   way. Also note that for linear cascades an explicit outlet unit operation is not required,
%   since the outlet profile of the last unit operation can be used instead.
