Hello, everyone.
I'm learning using matlab svm toolbox. And now I met a problem.
I know the svm needs a parameter called 'C', neither the linear svm nor unlinear.
But I don't know how to set the parameter to the funciton svmtrain() in matlab toolbox. Can anyone help me and give me some advice?

I tried :
svmtrain(data,group,'kernel_Function', 'rbf','C', 20);
svmtrain(data,group,'C', 20);
svmtrain(data,group, '-C', 20);

They are all wrong....
Thank you in advance.
