What really makes this book so nice is that very little background is assumed (a little bit of mathematical analysis and some background in numerical analysis would help) and it is very straightforward to code up (I used Matlab) the examples sprinkled throughout the text. I also liked the...
For example, Hpsd = psd(Hs,X,Hopts,'SpectrumType', 'twosided') overrides the SpectrumType value in Hopts. The following properties apply to both psdmopts and psd methods. Hpsd = psd (Hs,X,'SpectrumType','twosided') returns the two-sided power spectral density of X. The spectrum ...

For details about these spectral matching methods, see Algorithm. Data Types: char | string MinBandWidth— Minimum overlap bandwidth 300 (default) | positive scalar Minimum overlap bandwidth, specified as the comma-separated pair consisting of 'MinBandWidth' and a positive scalar in nanometers. The...
This MATLAB function estimates the frequency response, along with uncertainty, and the noise spectrum from time- or frequency-domain data data.
In order to compute it, one has to take the deviation of the spectrum from the spectral centroid, according to the following equation: (4.9)Si=∑k=1WfL(k-Ci)2Xi(k)∑k=1WfLXi(k). The MATLAB code that computes the spectral centroid and spectral spread of an audio frame is presented ...
3.3 Spectral methods LES has a very definite advantage: it can deal with flows which are not in spectral equilibrium. Another approach to take those flows into account is to use the so-called spectral models, by which one keeps information on the turbulence spectrum. To do so, one derives ...
Note that although, the spectrum of DDEs cannot be expressed in closed form, there are several well developed methods for the solution of the quasi-polynomial characteristic equation, for example, the contour integration based method [59] or the quasi-polynomial root finder [60]. Other algorithms...
Lagrangian formulations, free-boundary problems, infinite elements, and dis- v vi Finite and Spectral Element Methods using Matlab continuous Galerkin methods, are briefly mentioned in Appendix F entitled “Glossary,” which is meant to complement the subject index. This text has been written ...
Use codegen (MATLAB Coder) to generate a MEX function. The %#codegen directive in the function indicates that the MATLAB® code is intended for code generation. The -args option specifies example arguments that define the size, class, and complexity of the inputs to the MEX-file. For this...
