Hi,
after i make my model using 'fitcsvm' and predict the test data, id like to know the boundary and plot it
i cant find anything inside the model variable (1x1 ClassificationSVM) but i cant find anything thats like points so i can plot the line
heres the code i use if needed:
model=fitcsvm(trainD',trainL','Standardize',1);
trainD is 2x200 (100 for each class and 2 features)
ALSO
for some reason i dont understand, using linear svm gives me 100% accuracy while non lienar gives me about 75% (test data is too little 12 sample each)
