How to avoid unrecognized option names using optimget
显示 更早的评论
I am using lsqcurvefit and receiving errors related to the function lsqncommon. I did not have these errors in the past, so this may be due to changes with more recent versions of Matlab. How can I edit the lines below to avoid these errors? Thank you.
Error 1. "Unrecognized option name 'InitDamping'. See OPTIMSET for possibilities."
Relevant lines of lsqncommon:
algorithm = optimget(options,'Algorithm',defaultopt,optimgetFlag);
initDamping = optimget(options,'InitDamping',defaultopt,optimgetFlag);
if ~iscell(algorithm)
initLMparam = initDamping;
else
initLMparam = algorithm{2}; % Initial Levenberg-Marquardt parameter
algorithm = algorithm{1}; % Algorithm string
end
Error 2. "Unrecognized option name 'ProblemdefOptions'. See OPTIMSET for possibilities."
Relevant lines of lsqncommon:
ProblemdefOptions = optimget(options, 'ProblemdefOptions',defaultopt,optimgetFlag);
FromEqnSolve = false;
if ~isempty(ProblemdefOptions) && isfield(ProblemdefOptions, 'FromEqnSolve')
FromEqnSolve = ProblemdefOptions.FromEqnSolve;
end

You should not edit MathWorks-authored files. Show us the code that you wrote and are running, and let's discuss changes to that.

I wonder whether those are options that are present only if you have Global Optimization Toolbox installed?

You need to provide a simplification of your code that we can run and reproduce the error. The code structure you've outlined looks fine, and works fine in the online Matlab engine, as demonstrated below,
[MaxFunEvals,MaxIter,TolFun,TolX,TolOpt]=deal(1e6,100,1e-6,1e-6,1e-6);
function_handle=@(p,xd) xd+p;
X_data=1:5;
Y_data=X_data+pi;
Parameters_Guess=3;
[Parameters_Lower, Parameters_Upper]=deal(0,10);
options = optimoptions('lsqcurvefit', ...
'Display', 'off', ...
'MaxFunctionEvaluations', MaxFunEvals, ...
'MaxIterations', MaxIter, ...
'FunctionTolerance', TolFun, ...
'StepTolerance', TolX, ...
'OptimalityTolerance', TolOpt, ...
'Algorithm', 'trust-region-reflective');
[Parameters_Fit, RSS, residual, exitflag, output, ~, jacobian] = ...
lsqcurvefit(function_handle, Parameters_Guess, ...
X_data, Y_data, ...
Parameters_Lower, Parameters_Upper, ...
options)

Note that the user is using R2024a, but MATLAB Answers is using R2024b. The lsqncommon routine was rewritten between the two versions, and no longer has the problematic call.

I can't find any documentation of that. I don't think we've even identified what the "problematic call" is, because we haven't seen the OP's actual code.
When I run the hypothetical code that I proposed in R2024a, it still runs fine.

Although I am using R2024a, that particular code still uses an older (2016-2019) version of lsqcurvefit.
If so, problem solved. Use the version of lsqcurvefit that accompanies R2024a. It is obviously dangerous and unpredictable to mix Mathworks-authored files from different Matlab releases.
