  A recently proposed rational-function approximation [Phys. Rev. E
\textbf{84}, 041201 (2011)] for the structural properties of nonadditive hard
spheres is applied to evaluate analytically (in Laplace space) the local
density profiles of multicomponent nonadditive hard-sphere mixtures near a
planar nonadditive hard wall. The theory is assessed by comparison with $NVT$
Monte Carlo simulations of binary mixtures with a size ratio 1:3 in three
possible scenarios: a mixture with either positive or negative nonadditivity
near an additive wall, an additive mixture with a nonadditive wall, and a
nonadditive mixture with a nonadditive wall. It is observed that, while the
theory tends to underestimate the local densities at contact (especially in the
case of the big spheres) it captures very well the initial decay of the
densities with increasing separation from the wall and the subsequent
oscillations.
