Hi,
Is the a way to do parameter estimation using Least Absolute deviation with constraints in matlab.
If so, please let me know of a place to read about it.
thanks.

If you are talking about the problem
min_x sum( abs(r(x)))
it is equivalent to
min_{x,d} sum(d)
s.t.
r(x) <=d
-r(x)<=d
The above formulation is differentiable if r(x) is differentiable, so FMINCON can handle it. You can obviously add any additional constraints you wish, so long as they too are differentiable.
