  • A note on Lanczos generalized derivative 

    López Bonilla, José Luis; Iturri-Hinojosa, Alejandro; Bucur, Amelia (Venezuela, 2010-11-02)
    Lanczos introduced an integral expression for calculating the derivative of a function, if this is continuous in the point x under analysis. Here we extend this expression to the case of a finite discontinuity at x.
