Training and testing the data

    I got a code from net for SVM classifier 

    clc
    clear all

    load fisheriris                              %# load iris dataset
    groups = ismember(species,'setosa');         %# create a two-class problem

    %# number of cross-validation folds:
    %# If you have 50 samples, divide them into 10 groups of 5 samples each,
    %# then train with 9 groups (45 samples) and test with 1 group (5 samples).
    %# This is repeated ten times, with each group used exactly once as a test set.
    %# Finally the 10 results from the folds are averaged to produce a single
    %# performance estimation.
    k=10;

    cvFolds = crossvalind('Kfold', groups, k);   %# get indices of 10-fold CV
    cp = classperf(groups);                      %# init performance tracker

    for i = 1:k                                  %# for each fold
        testIdx = (cvFolds == i);                %# get indices of test instances
        trainIdx = ~testIdx;                     %# get indices training instances

        %# train an SVM model over training instances
        svmModel = svmtrain(meas(trainIdx,:), groups(trainIdx), ...
            'Autoscale',true, 'Showplot',false, 'Method','QP', ...
            'BoxConstraint',2e-1, 'Kernel_Function','rbf', 'RBF_Sigma',1);

        %# test using test instances
        pred = svmclassify(svmModel, meas(testIdx,:), 'Showplot',false);

        %# evaluate and update performance object
        cp = classperf(cp, pred, testIdx);
    end

    %# get accuracy
    cp.CorrectRate

    %# get confusion matrix
    %# columns:actual, rows:predicted, last-row: unclassified instances
    cp.CountingMatrix

I have 5x6 samples

have divided 5x4 to training and 5x2 for testing

now please tell how to process above mentioned step

Hello!Can you give me the code of the function svmtrain? Thank you very much.

Answer 2

[noo no]

i have code in matlab how trining and testing this code?
