We will first focus on linear equality constraints and then generalize to the nonlinear case. The problem is cast as

$\begin{array}{ll}\hfill \underset{\mathit{\theta}}{min}& J(\mathit{\theta}),\hfill \\ \hfill \text{s.t.}& A\mathit{\theta}=\mathit{b},\hfill \end{array}$

where A is an m × l matrix and b, θ are m × 1 and l × 1 vectors, respectively. It is assumed that the cost function J(θ) is twice continuously differentiable and it is, in general, ...
