Vogel Approximation Method

The inversion of Laplace transforms is performed using two methods: (1) the Zakian method and (2) the Fourier series approximation. Results are in agreement with analytical solutions. The Zakian method presents problems for transcendental functions. The Fourier series gives better results when...

COMPOSITE SIMPSON's method for numerical calculations and analysis exercises of Numeric Integration. f function is given in terms of a symbolic variable x and as aninline function. E.g., inline('x^2+2*x-2'). Also, if the function f is trigonometric function, the 4th argument can be entered...

Metamaterial 1D simulation using FDTD method and its frequency response are presented on this codeMetamaterial is a double negative material where the effective permeability and permittivity are negative. So if we hit any Gaussian wave on the surface of DNG material then some part is reflected...

The code implements the shooting method by means of the Runge-Kutta method of 4th order and the interval bisection method. There is the graphical interface too. When the differential equation is inserted in terms of the standard mathematical notation (no in MATLAB code), the programme create the...

This function shows an approximation of the Julia set boundary for the functions of the form P(z) = z^2 + C. The inverse iteration is a method for calculating previous values of z by doing z = sqrt(z-c). By doing this, points along the boundary are obtained. Since the sqrt will give two possible...
