How do I numerically calculate a function from its noisy gradient using “global integration”?
I have the model $\ s(x,y)=x^2+y^2, 0 \leq x \leq 1, 0 \leq y \leq 1 $.
Instead of observing the model directly I am observing the derivatives of the model + some noise (e):
$\ p(x,y)=s_x+e, ...

Least Squares solution of linear equation using conjugate gradient method
I have two partial differential equations that I want to solve (for s) by finite differences:
$\begin{align*} \frac{\partial}{\partial x}s(x,y) &= p(x,y)\\
\frac{\partial}{\partial y}s(x,y) ...
