We propose a fast MATLAB implementation of the mini-element (i.e. P 1-Bubble/P 1)
for the finite element approximation of the generalized Stokes equation in 2D and
3D. We use cell arrays to derive vectorized assembling functions. We also propose
a Uzawa conjugate gradient method as an iterative solver for the global Stokes sys-
tem. Numerical experiments show that our implementation has an (almost) optimal
time-scaling. For 3D problems, the proposed Uzawa conjugate gradient algorithm
outperforms MATLAB built-in linear solvers.
