How to apply SVM algorithm to my dataset and do the cross validation

I have a data-set with different features. I have made all my train data with different features in it as X[3566X31] and I have label in y[3566X1]. I have my test data in Xtest[3566X31]. I want to apply my data to SVM algorithm and perform cross validation on training data-set itself. After getting the cross validation result I like to apply my test data to get accuracy result. Please anybody help me with the code.
