MATLAB: For cycle to extract row of an Array and save them into vectors

arrayfor loopMATLABvector

Hello All, need some help with the following. I have an Array (4×4 cell), cal it A, and I need to create a "for" cycle that allows me to extract and save each row to a single vector. Ideally in this case the resulting vectors would be r1, r2, r3, r4. Sizes of all the vectors would of course be [1 4]. Thanks!
