SPLISURF is a Matlab tool that performs the construction of local bivariate quadratic C^1 quasi - interpolating splines defined as a linear combination of B-splines, both on uniform and non uniform type-2 triangulations, as described in: C. Dagnino - P. Lamberti, On C^1 quasi-interpolating splines with type-2 triangulations. Progetto MURST "Analisi Numerica: Metodi e Software Matematico", Monografia n. 4, Ferrara (2000) where an overview of the main properties of such splines are presented, numerical and graphical results obtained by SPLISURF on a set of test functions are reported and the reference manual is given. Such monograph is available at the authors'. The software has been developed in the context of the MURST project "Analisi Numerica: Metodi e Software matematico" in the years 1998-2000.

Abstract
SPLISURF is a Matlab tool that performs the construction of local bivariate quadratic C^1 quasi - interpolating splines defined as a linear combination of B-splines, both on uniform and non uniform type-2 triangulations, as described in: C. Dagnino - P. Lamberti, On C^1 quasi-interpolating splines with type-2 triangulations. Progetto MURST "Analisi Numerica: Metodi e Software Matematico", Monografia n. 4, Ferrara (2000) where an overview of the main properties of such splines are presented, numerical and graphical results obtained by SPLISURF on a set of test functions are reported and the reference manual is given. Such monograph is available at the authors'. The software has been developed in the context of the MURST project "Analisi Numerica: Metodi e Software matematico" in the years 1998-2000.
