2. Problem In Matlab, create the plot shown below using two different methods. It is the surface of a sphere with radius one, centered at (0, 0,0). As background, you know that the equation of a sphere with center (xo, yo, zo) in cartesian coordinates is r' = (x-xo)2 + (y-yo)2 + (z-zo)2 for x in the range [xo-r, Xo+rl y in the range [yo-r, yo+rl z in the range [20-r, zo + r]. 0.5 a) b) Use Matlab's sphere function. Use Matlab's cylinder function. You will have to give the function a vector representing * the semi-circular profile that you want revolved around the z-axis. Note that cylinder will return values that are spaced along the z-axis from 0 to 1. You will have to scale them to get a sphere that isn't squashed. -1 0.5 0.5 0.5 0.5
