| Hello, The MatLab software has a toolbox for system identification techniques from data. What is the procedure to follow, what instructions should be used with Mathematica to have a system identification? Thanks |
| When I use PoissonPointProcess with my data, it is OK ClearAll["Global`*"] villes = Entity["Country", "France"]["LargestCities"]; data = SpatialPointData[villes] proc = EstimatedPointProcess[data, PoissonPointProcess[\[Lambda],... |
| In Help information we have this little program, that I modified Graphics[{White, CountryData["Italy", "Polygon"], PointSize[Large], Red, Point[Reverse[CityData[#, "Coordinates"]]] & /@ CityData[{Large, "Italy"}]}, ImageSize... |
| With version 11 this program work well. In data we have longitude, latitude and a number that indicate a class. And this program draw a map with stations. GeoListPlot[data[[All, All, 1]] , PlotLegends -> data[[All, 1, -1, 1]], ... |
| I have a table of 12 series of temperature. I calculate the linear model for these 1é series with ajust = Table[ LinearModelFit[tabmoymob[[i]], {1, x}, x], {i, 1, n1, 1}]; where n1=12; I have a good result : ![enter image... |
| Does Mathematica use the six cores of the new Mac book Pro 15 ? |
| I want to solve the Lokta Fisher model, a system of two differential partial equations that represents diffusion of two innovations around a City (Paris). I try with this program, but NDSolveValue don't accept to solve this system of non linear... |
| This program work finewithe Mathematica 11.2, but not with Mathematica 11.3. Why ? (*Equation reaction diffusion temporelle *) ClearAll["Global`*"] Needs["NDSolve`FEM`"] parisradius = 0.3; parisdiffusionvalue = 150; ... |
| I want to simulate urban growth in the French Riviera with a cellular automaton. The following program works and analyzes the results. Rule 1000 seems appropriate. St. Wolfram has classified the behavior of cellular automata. But can we have a... |
