Hi,

I have calculated the features of size <432*1> and has 3456 bytes but while saving feature vector of many images as separate mat file many file has 3KB size and few files have 2KB size due to this variation I am unable to concatenate the feature vectors of 1000 images so, please give some suggestions for this problem.

Do not concatenate .mat files themselves. Only concatenate values in the workspace. The size on disk of a .mat file is irrelevant, and can reflect how well the data is compressed rather than the number of elements in the array.
