Orcaflex simulation in Matlab - How to change variables automatically until results are satisfied?

This is my code. It's an interface between Matlab and Orcaflex software.
model = ofxModel('Model2.sim'); % Existing model in Orcaflex
% Create a new Line
line = model.CreateObject(ofx.otLine,'Line2');
line.EndAConnection = 'FPSO'; % Connect the Line top end to the Vessel
line.EndBConnection = 'Anchored'; % anchor the Line bottom end
% Set the Line end positions
line.EndAX = 36.0;
line.EndAY = 1.732;
line.EndAZ = -7.5;
line.EndBX = 900.0;
line.EndBY = 1.732;
line.EndBZ = 0.178;
% Set the section lengths
linetype = model('Flexible riser');
line.Length(1) = L(1);
line.Length(2) = L(2);
line.Length(3) = L(3);
%Save data and run simulation
model.SaveData('Model3.dat');
model.CalculateStatics;
model.RunSimulation;
model.SaveSimulation('Model3.sim')
RangeGraphResults = line.RangeGraph('Max von Mises Stress');
max_values1 = RangeGraphResults.Max;
RangeGraphResults = line.RangeGraph('Effective tension');
max_values2 = RangeGraphResults.Max;
% Effective tension
b = max(max_values2')
% Allowable tension
maxVal = 4329e3;
% Check if condition is met
if (b <= maxVal)
disp('Value within specified range.')
elseif (b > maxVal)
disp('Value exceeds maximum value.')
end
My question: Is it possible to re-run this simulation with different values of L(1), L(2) and L(3) until the condition is met automatically, where 875<L(1)<925, 165<L(2)<330 and 280<L(3)<380? Or at least change one variable?
