  We develop a matrix model to describe bilayered quantum Hall fluids for a
series of filling factors. Considering two coupling layers, and starting from a
corresponding action, we construct its vacuum configuration at
\nu=q_iK_{ij}^{-1}q_j, where K_{ij} is a 2\times 2 matrix and q_i is a vector.
Our model allows us to reproduce several well-known wave functions. We show
that the wave function \Psi_{(m,m,n)} constructed years ago by Yoshioka,
MacDonald and Girvin for the fractional quantum Hall effect at filling factor
{2\over m+n} and in particular \Psi_{(3,3,1)} at filling {1\over 2} can be
obtained from our vacuum configuration. The unpolarized Halperin wave function
and especially that for the fractional quantum Hall state at filling factor
{2\over 5} can also be recovered from our approach. Generalization to more than
2 layers is straightforward.
