README snapshot
Btwxt is a free and open source C++ library to perform numerical interpolation on a regular grid data set. The primary class is a RegularGridInterpolator constructed from: 1. a set of N grid axes representing the values of the independent variables, and 2. a collection of one or more grid point data sets aligned to the grid axes. A RegularGridInterpolator object can then be queried repeatedly for interpolated values that fall inside its grid points, or extrapolated values beyond the grid points (up to a limit defined by the us
