I have downloaded this code from internet. It gives (Error using svmtrain (line 259) TRAINING and Y must both contain at least one row with no missing values.

Error in svm_test (line 41) SVMStruct = svmtrain(arrayImage, class);) How to remove this error?

I want to show result in the form of image, how to do this? (it did not show any output)

clear all; 
clc; 
folder = 'RandomNoisrData'; 
dirImage = dir( folder ); 
numData = size(dirImage,1); 
M ={} ; 
%Read image data
for i=1:numData
    nama = dirImage(i).name;  
    if regexp(nama, '(DNoise|RNoise)-[0-2]{1,2}.jpg')
        B = cell(1,2); 
        if regexp(nama, 'Noise-[0-2]{1,2}.jpg')
            B{1,1} = double(imread([folder, '/', nama]));
            B{1,2} = 1; 
        elseif regexp(nama, 'VNoise-[0-2]{1,2}.jpg')
            B{1,1} = double(imread([folder, '/', nama]));
            B{1,2} = -1; 
        end
        M = cat(1,M,B); 
    end 
end
% Image conversion for SVM purposes
numDataTrain = size(M,1); 
class = zeros(numDataTrain,1);
arrayImage = zeros(numDataTrain, 300 * 300);
for i=1:numDataTrain
    im = M{i,1} ;
    im = rgb2gray(im); 
    im = imresize(im, [300 300]); 
    im = reshape(im', 1, 300*300); 
    arrayImage(i,:) = im; 
    class(i) = M{i,2}; 
end
SVMStruct = svmtrain(arrayImage, class);
% Test for Random Noise
lionTest = double(imread('RandomNoiseData/TestImage3.jpg' )); 
lionTest = rgb2gray(lionTest); 
lionTest = imresize(lionTest, [300 300]); 
lionTest = reshape(lionTest',1, 300*300); 
result = svmclassify(SVMStruct, lionTest);  
result;
