摘要: Abstract. Power basis polynomial is the most simple polynomial function. It also be called power series. OpenCASCADE provides basic computation functions for polynomial functions, such as evaluate the result for a given polynomial, Lagrange interpolation, Hermite interpolation, .etc. The package named PLib, means Polynomial functions Library. The paper focus on the Lagrange interpolation usage of PLib.
Key Words. OpenCASCADE, PLib, Interpolation, Lagrange, 插值
