The change of basis matrix M from shifted Legendre to Bernstein polynomials and M−1 have applications in computer graphics. Algorithms use their properties to find the matrix elements efficiently. We give new functions for the elements of M as a su

A Collocation Numerical Method for Highly Oscillatory Algebraic Singular Volterra Integral Equations
Publikováno v:
Fractal and Fractional, Vol 8, Iss 2, p 80 (2024)
The highly oscillatory algebraic singular Volterra integral equations cannot be solved directly. A collocation numerical method is proposed to overcome the difficulty created by the highly oscillatory algebraic singular kernel. This paper is composed
