I have extracted 110 features of an image and input them in a features vector A:

A=[f1,f2,f3,f4....,f110];

How can i create a function that'll take a folder path as input and extract the features of every image and place it in a file to create a matrix of feature vectors of each sample , each row represent the parameters of a different sample and each column represent a different feature. Note that'll need to call those vectors back from the database in the main code.
