I need to be able to pass some data of my own, that is inputted by a user, into the surrograteopt function in order to have it work properly. Here is the code I have: (most of it, I removed a lot of the code within the function because it is not useful in this scenario. The function works perfectly, until I added these inputs)
clear;
clc;
addpath ../
nvar = 2;
upperBounds = [10,10];
lowerBounds = [1,1];
intcon = 1:nvar;
inputs = inputCaller();
[unitCostLaborFile, unitCostLaborPath] = uigetfile('*.xlsx','Select file with Welding Unit Costs for labor');
[unitCostFile, unitCostPath] = uigetfile('*.xlsx','Select file with Welding Unit Costs for equipment');
[weldSpeedsFile, weldSpeedsPath] = uigetfile('*.xlsx','Select file with Welding Speeds from WPS');
% Set nondefault solver options
options = optimoptions('surrogateopt','MaxFunctionEvaluations',10,'PlotFcn',...
[]);
% Solve
[solution,objectiveValue] = surrogateopt(@objConstrFcn,lowerBounds,...
upperBounds,intcon,[],[],[],[],options);
% Clear variables
clearvars options
% disp(solution);
% disp(objectiveValue);
fill = solution(1);
cap = solution(2);
cost = objectiveValue;
print(fill,cap,cost);
function f = objConstrFcn(optimInput, inputs, unitCostLaborFile, unitCostFile, weldSpeedsFile)
startDateInput = inputs(1);
endDateInput = inputs(2);
pipeSize = inputs(3);
pipeThickness = inputs(4);
welds = inputs(5);
workHours = inputs(6);
travelTime = inputs(7);
weight = inputs(8);
overhang = inputs(9);
qaqc = inputs(10);
useTackRig = inputs(11);
Does anyone know how I would make this possible? This is pretty integral to my program, as without these user inputs I won't get the proper utilization of this program.

To pass extra parameters see Passing Extra Parameters.
