Hello,I am using libsvm to classify data into 60 classes.size of my train matrix is 360*200.360 is the number of observstion and 200 is the number of features. I use libsvm from here: https://www.researchgate.net/post/How_can_I_use_Libsvm_in_matlab_for_multi-class_SVM. I recieve this error:
Index exceeds matrix dimensions.
Error in OVR (line 48)
trainData = data(trainIndex,:);
Error in sample (line 99)
[predictedLabel, decisValueWinner, totalAccuracy, confusionMatrix, order] = OVR(label,
ndata, runCVIndex, Ncv_classif, optionClassif);
can any one help me solve this problem.
