We characterize functions with a given degree of nonlinear approximation by linear combinations with n terms of a function π, its dilates and their translates. This gives a unified viewpoint of recent results on nonlinear approximation by spline functions and give their extension to functions of several variables. Our approach is formulated in terms of wavelet decompositions.
