Not enough input arguments for multivariable function when using bayesopt.

Question

0 个投票

I want bayesopt to minimize two variables in a particular function. This piece of code works with one function (just var,) but the second I try to add var1 and its corresponding y input into the function all I get is "not enough input arguments." The error sites the "fun = ..." line as the one with the error.

Here is my code and its corresponding error:

var = optimizableVariable('theta',[1,10],'Type','real');

var1 = optimizableVariable('alpha',[1,10],'Type','real');

fun = @(x,y)objfunxx(x.theta, y.alpha); %Create Function Handles

results = bayesopt(fun,[var,var1]);

Not enough input arguments.

Error in solution>@(x,y)objfunxx(x.theta,y.alpha) (line 4)
fun = @(x,y)objfunxx(x.theta, y.alpha); %Create Function Handles

Error in BayesianOptimization/callObjNormally (line 13)
Objective = this.ObjectiveFcn(conditionalizeX(this, X));

Error in BayesianOptimization/callObjFcn (line 25)

Error in BayesianOptimization/runSerial (line 24)

Error in BayesianOptimization/run (line 9)

Error in BayesianOptimization (line 184)
this = run(this);

Error in bayesopt (line 323)
Results = BayesianOptimization(Options);

function f = objfunxx(x,y)

f=y*sin(x);

end
