摘要：
This paper gives a type of new spline quasi-interpolants where the entry values are integral values of successive intervals, rather than the usual function values at the knots. They are called integro spline quasi-interpolants. Also, their super convergence property in approximating function values/derivative values at the knots/mid-knots are proved. Numerical experiments show that the integro spline quasi-interpolants possess super convergence.
