Witryna3 maj 2016 · Hey guys. I am fairly new with matlab. Currently i am trying to animate the change of a velocity field in a fluid in time. The velocity field is dependent on depth (z) and distance (x). I would like to present the velocity field in a x/z coordinate system and by an animation show how it changes with time. Witryna8 lis 2024 · The relationship depends on a ( t) and the curvature k. In principle, if we measure distances and redshifts for objects at a variety of distances we could then infer a ( t) and k. The general relationship between redshift and luminosity distance is contained in these equations: (8.6) c ∫ a e 1 d a a 2 H = ∫ 0 d d r 1 − k r 2. google smart watch uk https://crs1020.com
