save('NameOfMatFile.mat', 'MEAN', 'SD', 'ENTROPY', 'RMS' and so on)
This assumes that you have stored the value you labelled MEAN in a variable named MEAN .
If you have a bunch of uicontrol edit boxes then it is possible to extract their String properties and save those, but since you are extracting features from an image you have already calculated those into variables and you might as well save the numeric variables directly.

This helps me but I want it to save as one file not as individual. Like, the mean,sd,entropy ... will save in one mat file. ( Like the image below but in .mat file )

The way Walter showed you will save it as one mat file. All the variables you list will be in that same mat file. Try it and see. Use load() to read them back out of the mat file.

Loop over the blobs or images, for each construct a row vector of the properties you want in the order you want. Use each of those row vectors as a row in a matrix. At the end, save the matrix.
