sequentialfs fun problem

the example in matlab of sequentialfs
load fisheriris;
X = randn(150,10);
X(:,[1 3 5 7 ])= meas;
y = species;

c = cvpartition(y,'k',10);
opts = statset('display','iter');
fun = @(XT,yT,Xt,yt)...
(sum(~strcmp(yt,classify(Xt,XT,yT,'quadratic'))));

[fs,history] = sequentialfs(fun,X,y,'cv',c,'options',opts)

how can I get fun for any other classifier like(classify) if I have (xtrain, ytrain, xtest, ytest) for that classifier but I can't run the other classifier in 1 step to get its fun like the LDA classifier:

fun = @(XT,yT,Xt,yt)...
(sum(~strcmp(yt,classify(Xt,XT,yT,'quadratic'))));

if I have (xtrain, ytrain, xtest, ytest) how can I use sequentialfs function??
