Given a non-uniform criss-cross partition of a rectangular domain Ω, we analyse the error between a function f defined on Ω and two types of C1-quadratic spline quasiinterpolants (QIs) obtained as linear combinations of B-splines with discrete functionals as coefficients. The main novelties are the facts that supports of B-splines are contained in Ω and that data sites also lie inside or on the boundary of Ω. Moreover, the infinity norms of these QIs are small and do not depend on the… CONTINUE READING
