Using weka in matlab : Undefined weka.core.converters.MatlabLoader

I met a problem when i was trying to use weka in matlab.

Can anyone help me? 

WEKA_HOME = 'C:\Program Files\Weka-3-8';
javaaddpath([WEKA_HOME '\weka.jar']);
loader = weka.core.converters.MatlabLoader();

Then i got error message : 

Undefined variable "weka" or class "weka.core.converters.MatlabLoader".
Solution

  • Try to import the modules you use like shown in the following example:

    javaaddpath('C:\Program 

Files\Weka-3-9\weka.jar');

import weka.core.Attribute.*;

import weka.core.Instances.*;
import weka.core.DenseInstance.*;
import weka.classifiers.Classifier.*;
import weka.classifiers.bayes.BayesNet.*;
import weka.classifiers.Evaluation.*;
import weka.filters.Filter.*;
import weka.filters.unsupervised.attribute.Remove.*;
