Unable to generate java code for a trained classification data

Hi People. I got raw sensor raw. Now the training and testing of data is done.The problems am facing are a)for testing I need to have same length of data(rowXcolumn). I have random data of unequal length with large data sensor data. How can I pass my data? b)While testing I can check only the validation Accuracy I want to get the simulation as shown in attached screenshot(ref). How can I get it? c) When am trying to generate the java I get the following error I don't understand what it is? The following is the error? %mcc -W 'java:trainClassifier,Class1' -T link:lib -d F:\MATLAB\bin\trainClassifier\for_testing class{Class1:C:\Users\DeLL\Desktop\trainClassifier.m} The system cannot find the path specified. Error: An error occurred while shelling out to javac (error code = 1). Unable to build executable. For more information, pass the -v option to mcc.%
