Functions to create grids suitable for PDE pricing.
## Functions
[`log_uniform_grid(...)`](../../../tf_quant_finance/math/pde/grids/log_uniform_grid.md): Creates a grid spec for a uniform grid in a log-space.
[`log_uniform_grid_with_extra_point(...)`](../../../tf_quant_finance/math/pde/grids/log_uniform_grid_with_extra_point.md): Creates a grid for a uniform grid in a log-space with an extra grid point.
[`rectangular_grid(...)`](../../../tf_quant_finance/math/pde/grids/rectangular_grid.md): Specifies parameters for an axis-wise non-uniform grid in n-dimensions.
[`uniform_grid(...)`](../../../tf_quant_finance/math/pde/grids/uniform_grid.md): Creates a grid spec for a uniform grid.
[`uniform_grid_with_extra_point(...)`](../../../tf_quant_finance/math/pde/grids/uniform_grid_with_extra_point.md): Creates a grid spec for a uniform grid with an extra grid point.
