SPOD() is a Matlab implementation of the frequency domain form of proper orthogonal decomposition (POD, also known as principle component analysis or Karhunen-Loève decomposition) called spectral ...

In the world of engineering, MATLAB is more than just a tool—it's a universal language for simulation, analysis, and innovation. But its true power is unlocked when you apply its fundamentals directly ...

Abstract: In modern wireless communication systems, FFT is one of the key components but requires wide numerical dynamic range. In order to satisfy both requirements of smaller chip size and wider ...

MATLAB (short for Matrix Laboratory) is a powerful software tool used for technical computing and visualization. It is widely used in a variety of fields, including engineering, science, finance, and ...

DIFFT is an open-source collection of implementations for the Double-Interpolation FFT method proposed in the paper "An Improved Accuracy Harmonic Extraction Method for Microcontrollers" (Tian & Zhang ...

Several materials and tissues are characterized by a microstructure composed of fibrous units embedded in a ground matrix. In this paper, a novel three-dimensional (3D) Fourier transform-based method ...

We simulate an emerging GHz ultrasonic wave piezoelectric instrument for computing Fourier transforms. The techniques include ray tracing, Fresnel diffraction and full-wave finite element method (FEM) ...

The fault diagnosis of the inverter is fundamental to energy intelligence. Due to the complex characteristics of the inverter (e.g., high-dimensional decision and poor stability), it is challenging to ...
