Error in the brain tumor detection code

I am doing project on brain tumor detection classification.I run the code from the math work.I am getting about svmtrain and svmclassify and I changed the syntax of that but still I am getting errors.

ERROR:

Name Size Bytes Class Attributes

DWT_feat 31x124 30752 double

G 124x30 29760 double

Error using classreg.learning.FitTemplate/fillIfNeeded (line 666)

As @Don Mathis points out in https://www.mathworks.com/matlabcentral/answers/478038-getting-error-kernel-function-is-not-a-valid-parameter-name#answer_390234

the parameter name is 'KernelFunction'

But still error exists.

Error:

DWT_feat 31x124 30752 double

Name Size Bytes Class Attributes

G 124x30 29760 double

Error using ClassificationSVM (line 249)

Use fitcsvm to train an SVM model.

Error in BrainMRI_GUI>pushbutton2_Callback (line 182)

species = ClassificationSVM(svmStruct1,feat,'showplot',true);

Error in gui_mainfcn (line 95)

feval(varargin{:});

Error in BrainMRI_GUI (line 46)

gui_mainfcn(gui_State, varargin{:});

Error in

Error while evaluating UIControl Callback.
