Did you read the corresponding docs already? See: https://www.mathworks.com/help/vision/ref/extracthogfeatures.html#outputarg_features . Which detail is not clear yet? It would not be efficient to rephrase the complete help text.

because you are using blocksize as a number 4,,, instead, replace blockSize by the array [2 2]
