The difference is now that this function is a separate function that is used to solve the cubic equation. Finally, do test your program for the right answers! check the roots obtained by your program ...

Cubic spline interpolation is performed by passing through all the given data points, while the points between the data points are cubic. Therefore we define a piecewise cubic function between the ...

First, we provide an introduction into spline regression and describe linear- and restricted cubic spline regression in the context of an empirical data example. Then, we illustrate the application of ...

Nonlinear spectral analysis and numerical simulations are used in the study. The drag force expression is approximated by a cubic function whose coefficients are determined by equating the ...

Abstract We consider the cubic nonlinear Schrödinger (NLS) equation set on a two-dimensional box of size L with periodic boundary conditions. By taking the large-box limit L → ∞ in the weakly ...

Abstract:In this paper, an integrated cubic phase function (ICPF) is introduced for the estimation and detection of linear frequency-modulated (LFM) signals. The ICPF extends the standard cubic phase ...
