From a set of 3000 images, I have extracted HOG (dimension: 3000*6084 single) and LBP (dimension: 3000*10) features. How can I concatenate these features of different lengths?

They have the same number of rows, so you can concatenate horizontally

How to index the features with their names in the table.
(Due to their long dimensions how to automatically distinguish the feature index)
