How can I use use classification learner App in matlab?

I'm new to Matlab, I'm wondering if someone can help me to get start with machine learning task.

I would like to perform Linear discriminant analysis (LDA) or support vector machine (SVM) classification on my small data set (matrix of features extracted from ECG signal), 8 features (attributes). The task is binary classification into a preictal state (class 1) and interictal state (class 2).

In Matlab, I found (Classification learner app), which enable using different kinds of classifiers including SVM, but I don't know if I can use the input data that I have to train the classifier in this app?. I'm not sure how to start? Do you have any idea about this app? please help!
