Delete first row of a two-dimensional array

Question

Hey Guys!
I'm new here and I have a question.
I have a array with two dimension. I wanna delete the first row of my two-dimensional array and copy/fill it in a one-dimensional array. My problem is the two-dimensional array. How can I delete the first row and reduce this array?? I have a lot of datasets so I need a quick/the quickest way?
Could you help me? That would be great! Thanks!!
