[tf, history] = sequentialfs(...)
sequentialfs selects features from the columns of the first data input using a user supplied criterion function.
Supported options include CV, Direction, KeepIn, KeepOut, NFeatures, NullModel, and Options. CV can be a positive integer, none, or resubstitution.
The history structure contains In and Crit fields describing the selected feature mask and criterion value at each step.
X = [1 0 0; 2 0 1; 3 1 0; 4 1 1; 5 2 0; 6 2 1];
y = X(:,1);
fun = @(Xt,yt,Xv,yv) sum((yv - Xv(:,1)).^2);
