In my project I have 100 images for brain tumor classification. All images have glcm Feature extracted data. But I need to store all images data into single excel sheet at the time feature get extracted. I tried some code but it can over right on the previous data in the excel sheet. How can I store all data in single excel sheet.

In the loop, something like...

xlData = cell(numImage, 3);
for k = 1 : numImages
    filename = .......
    thisImage = imread(filename);
    glcm = graycomatrix(thisImage);
    stats = graycoprops(glcm,{'Contrast','Homogeneity'})
    xlData{k, 1} = filename;
    xlData{k, 2} = stats.Contrast;
    xlData{k, 3} = stats.Homogeneity;
end
xlswrite(xlFileName, xlData);

Add more measurements to stats if you want.

But when i am use above code i met with an error.

The error shown in the command window is given below...

Undefined variable "featureset" or class "featureset.xls".

Error in newpro (line 99) xlswrite(featureset.xls,xlData);

how can i resolve this error

It needs to be a string, in single quotes:

xlswrite('featureset.xls',xlData);

or better yet

xlFileName = fullfile(pwd, 'featureset.xlsx')
xlswrite(xlFileName, xlData);
