Detailed Description

The grid is defined as:

$x_0 = x_{low}$

$x_{i+1} = x_i + i \delta_x$

for $i=1,\dots,N$ , where $\delta_x = \frac{x_{upp} - x_{low}}{N}$

Below the code generating 2d grid and its visualization.

UniformGridBuilder ugb;
auto grid1 = ugb.buildGrid(0.0, 10.0, 25);
auto grid2 = ugb.buildGrid(0.0,  5.0, 20);
for (auto x : grid1) {
  for (auto y : grid2) {
    std::cout << x << ";" << y << std::endl;
  }
}

Examples:: convergenceExample.cpp, EuroOptExample.cpp, and FokkerPlanckEqExample.cpp.
