| I have a series of time values in a file called t = Flatten[Import["tiemposUniformesArticulo2022.txt", "Table"]]; and a series of values in a similar file in meanis4RVAB = Flatten[Import["meanis4RV_AB.txt", "Table"]]; I can... |
| Hello everyone. I want to save Gaussian random points in a txt file and then load them and calculate the empiric pdf. However, I am getting an error if the number of elements is high enough. To keep it simple, I have prepared a small example. ... |
| Hello everyone. I am working with some Monte Carlo simulations of a random variable. I want to use SeedRandom to store the results. My original code is as follows: empiricPDF1 = SmoothKernelDistribution[RandomVariable1Histogram]; d1 =... |
| Best way to sample times of different interpolations. Hello everyone. I have 50 vectors of position vs time. The measurement moments are different for each one of the 50. I have interpolated them as ... |
| Hello everyone. I have a set of weather data, wind in the East-West direction downloaded from the ECMWF. It is avaiable freely [here][1], albeit it needs some processing. I want to use the [Shannon interpolation][2] to obtain an analytic... |
| Hello everyone. I have performed the [Karhunen Loève decomposition][1] of some data using the function [KarhunenLoeveDecomposition][2]. The code I have used is as follows: R1 = Flatten[Import["Realization1.txt", "Table"]] {bT, mT} =... |
| Hello everyone. I am trying to read a .mat file created using another language, it's dimensions are 50*10. The code I am using is Clear["Global`*"] SetDirectory[NotebookDirectory[]]; dataText =... |
| Hello. I have some questions on how to implement propperly the KL expansion in mathematica using [KarhunenLoeveDecomposition][1]. I have constructed the matrix realizationMat. it contains 101 measurements of 90 Gaussian stochastic processes. I... |
| I am trying to generate a Gaussian random process usign the Karhunen-Loève expansion. I have the eigenvectors and eigenvalues of a Gaussian kernel, a matrix of size 101*101 and a vector of length 101. I need to multiply each eigenvector for the... |
| Hello everyone. I have a vector called stochasticData.mat which size is 211302*50 and I need to perform the karhunen-Loève decomposition on it to calculate the [uncorrelated random variables][1]. Note that stochasticData.mat has 50 realizations of a... |
