“…Barycentric rational interpolation not only has high interpolation accuracy on special distributed nodes but also has high interpolation accuracy for equidistant nodes [5][6][7]. is method has been used to solve certain problems such as Volterra integral equations [2,8,9], delay Volterra integrodifferential equations [10,11], plane elastic problems [12], nonlinear problems [13], heat conduction equation [14], and so on [15][16][17].…”
