You've mis-spelled your function call. In the tester function, change the line 
below ...

         w(i) = SVM_Linear(Xtrain,Ytrain,c);

to ...

         w(i) = SVM_linear(Xtrain,Ytrain,c);

The "L" should be lower case, "l"

You'll discover additional errors. For example, SVM_linear() returns a vector 
which will throw an error when you try to store it in the scalar w(i). Since I 
don't understand what you're trying to do, you'll have to either explain in 
detail or change the code.
