SVM train and Classification Errors

Hello Everyone im getting this weird error while im using svm train and classificationSvm. Need some help fixing it as i am new to this

Code Block: load Trainset.mat

xdata = meas;

group = label;

svmStruct = fitcsvm(xdata,group,'HyperparameterOptimizationOptions', struct('showplot',true), 'KernelFunction','rbf','KernelScale',0.5);

species = ClassificationSVM(svmStruct,feat,'showplot',true);

if strcmpi(species,'MALIGNANT')

helpdlg(' Malignant Tumor ');

disp(' Malignant Tumor ');

else

helpdlg(' Benign Tumor ');

disp(' Benign Tumor ');

end

set(handles.edit18,'string', species);

and the errors are

Error using ClassificationSVM (line 249)

Use fitcsvm to train an SVM model.

Error in untitled2>pushbutton12_Callback (line 615)

species = ClassificationSVM(svmStruct,feat,'showplot',true);

Error in gui_mainfcn (line 95)

feval(varargin{:});

Error in untitled2 (line 42)

gui_mainfcn(gui_State, varargin{:});

Error in

matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)untitled2('pushbutton12_Callback',hObject,eventdata,guidata(hObject))

Error while evaluating UIControl Callback.

Anybody has any idea in what im doing wrong? any help will be appreciated :)

Try removing the line

 species = ClassificationSVM(svmStruct,feat,'showplot',true);

To learn how to use the resulting SVM, see the documentation for fitcsvm.

Hello.

load Trainset.mat has two file. one of these meas and label.

When I see meas files. I saw 20*13 matrix. what is the meaning. Why the file is 20*13 matrix
