AbstractThe band method is a flexible method for solving a variety of interpolation and extension problems which has evolved into increasing levels of sophistication over the past two decades. This article enhances the Grassmannian version of the band method to handle the Nehari–Takagi problem rather than merely the Nehari problem.
