[Mathimatics-Numerical algorithms] Euler DL : 0: Euler方法用C语言实现，并求解常微分方程组-The m framework appropriately generalizes notions such as gain margin, phase margin, disturbance attenuation, tracking, and noise rejection into a common framework suitable for analysis and design, in both single-loop and multiloop feedback systems. Even when working with single-loop feedback systems, some multi-input, multi-output (MIMO) systems arise during the analysis. Hence, a unified framework to deal with MIMO linear systems is important, with full support for both the time and frequency domain. m-Tools provides the capability to build complex interconnections (such as cascade, parallel, and feedback connections), compute properties (such as poles and zeros), calculate time and frequency responses, manipulate these responses (FFT for the time domain signals, Bode analysis for the frequency domain functions), and plot results. m-Tools supports two data types in addition to the standard matrices: SYSTEM matrices for state-space realizations

[matlab] first DL : 1: 二维傅里叶变换,对图像进行二维傅里叶变换处理-Two-Dimensional Fast Fourier Transform The purpose of this project is to develop a 2-D FFT program "package" that will be used in several other projects that follow. Your implementation must have the capabilities to: (a) Multiply the input image by (-1)x+y to center the transform for filtering. (b) Multiply the resulting (complex) array by a real function (in the sense that the the real coefficients multiply both the real and imaginary parts of the transforms). Recall that multiplication of two images is done on pairs of corresponding elements. (c) Compute the inverse Fourier transform. (d) Multiply the result by (-1)x+y and take the real part. (e) Compute the spectrum.

[Software Engineering] radix2 DL : 0: fft The radix-2 algorithms are the simplest FFT algorithms. The decimation-in-time (DIT) radix-2 FFT recursively partitions a DFT into two half-length DFTs of the even-indexed and odd-indexed time samples. The outputs of these shorter FFTs are reused to compute many outputs

[DSP program] fft DL : 0: what is the DFT? The DFT is extremely important in the area of frequency (spectrum) analysis because it takes a discrete signal in the time domain and transforms that signal into its discrete frequency domain representation. Without a discrete-time to discrete-frequency transform we would not be able to compute the Fourier transform with a microprocessor or DSP based system.
