I'm trying to use sequential feature selection in a regression problem and I keep on getting errors. I know something is wrong with my function handle but can't figure it out. Tried these three handles:
%fun = @(XT,yT,Xt,yt)loss(regress(yT,XT),Xt,yt);
%fun = @(XT,yT,Xt,yt)rmse(predict(fitlm(XT,yT),Xt),yt);
%fun = @(XT,yT,Xt,yt)rmse(predict(regress(yT,XT),Xt),yt);
[fs,history] = sequentialfs(fun,X,y,'cv',c,'options',opts);

It would be very helpful if you post the full code, along with screenshots of error messages, this would help in quick resolution of issue

Hi azarang asadi,
The documentation link to the sequentialfs function is attached here. There is also an example that demonstrates how to use the function. I hope this helps with your query.
Thank you
