Detailed Description

LOCA-LAPACK problem interface for the Chan problem.

ChanProblemInterface implements the LOCA::LAPACK::Interface for a 1D finite-difference discretization of the Chan problem:

\[ \frac{d^2 T}{d x^2} + \alpha s \left(1 + \frac{x + 0.5 x^2}{1 + 0.01 x^2}\right) = 0 \]

subject to the boundary conditions $T(0) = T(1) = \beta$. The parameters are $\alpha$, $\beta$, $s$, and $n$, the size of the discretization. The scaling factor $s$ is used to test continuation at different scales of $\alpha$.
