Quadrature approximation properties of the spiral-phase quadrature transform
The notion of the 1-D analytic signal is well understood and has found many applications. At the heart of the analytic signal concept is the Hilbert transform. The problem in exte...

A two-dimensional separation of concerns for compiler construction
During language evolution, compiler construction is usually d along two dimensions: defining new abstract syntax tree (AST) classes, or adding new operations. In order to facilita...

Construction of Fractal Interpolation Surfaces on Rectangular Grids
We present a general method of generating continuous fractal interpolation surfaces by iterated function systems on an arbitrary data set over rectangular grids and estimate their...

Fast construction of hierarchical matrix representation from matrix-vector multiplication
We develop a hierarchical matrix construction algorithm using matrixvector multiplications, based on the randomized singular value decomposition of low-rank matrices. The algorith...

Fast construction of nets in low dimensional metrics, and their applications
We present a near linear time algorithm for constructing hierarchical nets in finite metric spaces with constant doubling dimension. This data-structure is then applied to obtain...
