i want to find fractional fourier transform of rectangular function x(t) of length 1 and plot the frequency spectrum by given code ? iftrue % f is signal vector and a =fractional order function[Faf] = frft2(f,a) error(nargchk(2, 2, nargin)); f0 ...
Fourier transform is one of the powerful mathematical tool used in the analysis of system of FSDDEs. Fourier transformation empowers us to work in frequency domain, where the analysis of FSDDEs and linearization become more controllable. We’ll explore how to apply the Fourier transform to a sy...

The main aim of this research is to propose, analyze, and simulate the HBV model using fractional calculus. The model yet has not been solved numerically by using the fractional trapezoidal method FTM. Numerical solutions are obtained under the MATLAB environment using the codeflmm2 by R. Garr...
Next, we compare the processing cost in different QR code patterns by the proposed method. Subsequently, the results of reconstructing the QR code by different weight functions are shown. The software environments for the comparison experiments are created in Matlab 2012b, and a computer of 8 GB...
the beam is transformed by a lens from the coordinate space into the Fourier domain, in which a phase-shift emulating the fractional diffraction is introduced by means of an appropriate phase plate. Then, the second lens casts the optical field back into the spatial form, which carries the ph...
FOURIER transformsMATLAB (Computer software)FOURIER analysisMATHEMATICAL analysisThe definition of the discrete fractional Fourier transform (DFRFT) varies, and the multiweighted-type fractional Fourier transform (M-WFRFT) is its extended definition. It is not easy to prove its unitarity. We use the ...
Finally, MATLAB simulations will be executed to confirm the results provided. Keywords: variable fractional-order; dynamical behavior; chaos; C0 complexity; largest Lyapunov exponents MSC: 37M20 1. Introduction Chaos theory (Devaney 1989) [1] is the concept that a slight change now might lead to...
It is possible to derive several FLMMs with second order of convergence, which mainly differ for stability properties; for this purpose, we refer the reader to the paper [26], where the MATLAB code FLMM2.m implementing three different FLMMs is also presented. The regularization operated by th...
