What work space values do i need to save separately to test Classification

 What work space values do i need to save separately to test Classification of a number of voice emotion recognition neural networks and compare a new input against several to give a result?  

 

     TrainingHappyInput = NNHappyTrainingInput;
    TragetHappy= ones(1,1536);
 % set to Happy = 2
   TragetHappy=TragetHappy*2;
net = newff([min(TrainingHappyInput) max(TrainingHappyInput)],[14 1],{'tansig' 'purelin'},'traingd');
net.trainParam.epochs = 2900;   %Maximum number of epochs to train
    net.trainParam.goal = 0.01;    %Performance goal
    net.trainParam.lr = 0.01;       %Learning rate
    net.trainParam.min_grad=1e-10;  %Minimum performance gradient
    net.trainParam.show = 25;       %Epochs between displays
    net.trainParam.time = inf;      %Maximum time to train in seconds

    HappyTestset=TrainingHappyInput(400:700);

    NetOutputHappyTestData = sim(net,HappyTestset);
subplot(2,1,1), 
       plot(TrainingHappyInput(400:700),TragetHappy(400:700),HappyTestset,NetOutputHappyTestData,'o')
       title('Accuracy of classification'); 
  HappyDiffTraining =   TragetHappy (400:700)- NetOutputHappyTestData;
     subplot(2,1,2), plot(HappyDiffTraining);
     title('Difference Between Trained/Targets');

     HappyClassifiedTrained = mean(NetOutputHappyTestData);

     if HappyClassifiedTrained > 1.8078
         disp('Emotion detected is HAPPY...!');
     else 
         disp('Not Classified as Happy');
     end
This is the code I currently have for a Happy emotion and will have a similar network for sad etc. Having never studied Matlab or signal processing to finish this project I need to test a voice sample against the neural networks and output which emotion has been detected. Happy is Target is set to 2 as in the code, sad will be 3, neutral 1 etc. I don't know what variables i need to collect from each workspace and how to compare a test sample to all the networks and have a decision produced. I think it will be similar to the if statement at the end of the code above but can't work what I need to do.

There are many fundamental problems.
 
 
 0. You have spelled Target wrong

 1. NEWFF with special cases NEWFIT (for curve"FITTING" and 
    regression) and NEWPR (for "P"attern "R"ecognition) are obsolete. 
    Their replacements are FEEDFORWARDNET, FITNET and PATTERNNET, 
    respectively. 

2. This leads to the obvious question: "WHAT VERSION OF MATLAB ARE 
  YOU USING???"

 3. I assume you have a recent version and should be using PATTERNNET. 
   So, see the documentation with simple examples obtained from the 
   commands

   help patternnet

and

    doc patternnet.
4. Additional examples and explanation can be obtained from searches in both the NEWSGROUP and ANSWERS.

USING MACHINE LEARNING CLASSIFICATION ALGORITHMS FOR DETECTING SPAM AND NON-SPAM EMAILS

    ABSTRACT We know the increasing volume of unwanted volume of emails as spam. As per statistical analysis 40% of all messages are spam which about 15.4 billion email for every day and that cost web clients about $355 million every year. Spammers to use a few dubious techniques to defeat the filtering strategies like utilizing irregular sender addresses or potentially add irregular characters to the start or the finish of the message subject line. A particular calculation is at that point used to take in the order rules from these email messages. Machine learning has been contemplated and there are loads of calculations can be used in email filtering. To classify these mails as spam and non-spam mails implementation of machine learning algorithm  such as KNN, SVM, Bayesian classification  and ANN  to develop better filtering tool.   Contents ABSTRACT 2 1.

Why are Fourier series important? Are there any real life applications of Fourier series?

A  Fourier series  is a way of representing a periodic function as a (possibly infinite) sum of sine and cosine functions. It is analogous to a Taylor series, which represents functions as possibly infinite sums of monomial terms. A sawtooth wave represented by a successively larger sum of trigonometric terms. For functions that are not periodic, the Fourier series is replaced by the Fourier transform. For functions of two variables that are periodic in both variables, the trigonometric basis in the Fourier series is replaced by the spherical harmonics. The Fourier series, as well as its generalizations, are essential throughout the physical sciences since the trigonometric functions are eigenfunctions of the Laplacian, which appears in many physical equations. Real-life applications: Signal Processing . It may be the best application of Fourier analysis. Approximation Theory . We use Fourier series to write a function as a trigonometric polynomial. Control Theory . The F
