I have a matrix from real space calculation from honeycomb lattice and I wish to Fourier transform the spatial part (of the data) to momentum space. However, FFT, FFT2 etc in matlab does not allow for variable (time or coordinate) inputs, one can only include the data, so there is no...
the transformed signal is a linear combination of N time samples. If the signal to be transformed is a sine function, then, ideally, all these N samples add up in one bin and cancel out in all other bins, such 1 In Matlab Simulink, this would be a “Sine Wave” block with amplitude...
Create FFT Pricer Object Use finpricer to create an FFT pricer object and use the ratecurve object for the 'DiscountCurve' name-value pair argument. Get outPricer = finpricer("fft",'DiscountCurve',myRC,'Model',HestonModel,'SpotPrice',100,'CharacteristicFcnStep', 0.2,'NumFFT',2^13) ou...
摘要: Explain why we use fftshift(fft(fftshift(x))) in Matlab instead of fft(x). An example is given. The example and Matlab codes are partially copied from Daniele Disco 's work in "A guide to the Fast Fourier Transform, 2nd Edition"....
Note that to keep things simple the only path is using qmake/make.By setting some parameters in the .pro file, one may choose between aac decoding using the faad_drm library or the fdk-aac library.The latter has the (potential) advantage of being able to decode xHE-AAC as well...
Answer to: Let random variable X be normal with mean 105 and variance 25. Find the probability P (110.5 < X < 111.5) (Use MATLAB build - in...

A specific set of parameters of the damage model leads to a specific set of statistical distributions of the first frequency for each location of the vehicle on the bridge. Experimental data for the development of damage models is limited mostly to beams tested in a lab, and there is a ...
Change detection can be applied to the amplitude or intensity, filtered or elaborated versions of the amplitude [2,13,14]. For example, in [15], a technique based on change detection applied to quantities related to the fractal parameters of the observed surface was developed to address change...
