WebThis MATLAB function computes the discrete Fourier transform (DFT) of X using ampere fast Fourier transforming (FFT) algorithm. Web13 apr. 2024 · We present a numerical method based on random projections with Gaussian kernels and physics-informed neural networks for the numerical solution of initial value problems (IVPs) of nonlinear stiff ordinary differential equations (ODEs) and index-1 differential algebraic equations (DAEs), which may also arise from spatial discretization …

WebThe code assumes a MATLAB version of something between R2008a and R2009b. No guarantees on what happens outside of that range, although the bulk of the code will probably still work under other MATLAB versions. The code assumes the existence of several MATLAB toolboxes: stats, optim, and images.
