How to input train data and test data (features of images) using SVM calssifier

This is the code that i have got for classification using SVM. Can any one tell me how should i input train data and test data in the code,...

% Classfication using SVM classifier.............

% 1. Load the sample data

load dataname

% 2. Create data, a two-column matrix containing sepal length and sepal width % measurements for 150 irises.

data = [meas(:,1), meas(:,2)];

% 3. From the species vector, create a new column vector, groups, to classify data % into two groups: data and non-data.

groups = ismember(dataset,'data');

% 4. Randomly select training and test sets.

[train, test] = crossvalind('holdOut',groups); cp = classperf(groups);

% 5. Train an SVM classifier using a linear kernel function and plot the grouped data.

svmStruct = svmtrain(data(train,:),groups(train),'showplot',true);

% 6. Add a title to the plot, using the KernelFunction field from the svmStruct % structure as the title.

title(sprintf('Kernel Function: %s',... func2str(svmStruct.KernelFunction)),... 'interpreter','none');

% 7. Use the svmclassify function to classify the test set.

classes = svmclassify(svmStruct,data(test,:),'showplot',true);

% 8. Evaluate the performance of the classifier.

classperf(cp,classes,test); cp.CorrectRate

% ans =

 % 0.9867

 % 9. Use a one-norm, hard margin support vector machine classifier by changing the 
% boxconstraint property.

figure svmStruct = svmtrain(data(train,:),groups(train),... 'showplot',true,'boxconstraint',1e6);

classes = svmclassify(svmStruct,data(test,:),'showplot',true);

% 10. Evaluate the performance of the classifier.

classperf(cp,classes,test); cp.CorrectRate

%ans =

 % 0.9867

did you solve it?

i am getting error in line 4:

Undefined function 'crossvalind' for input

arguments of type 'char'.

please help to solve it
