A quadrature method with variable step for solving linear Volterra integral equations of the second kind

In usual quadrature methods for solving integral equations, divide the integration interval (a, b) into n equal subintervals of the length h = (b − a)/n. In this article, we intend to divide the integration interval into n subintervals of different lengths, which solves linear Volterra integral equations more accurately than usual quadrature methods.
