Hello People I have been working on heat equation simulation using Julia Software. I was stuck with creating a surface plot (3d plotting) I have values of x,t and T (is a matrix) how to make 3d plot Please help me

Do you need the following examples? using Plots f(t, x) = exp(-x^2/(2t))/√(2π*t) u(t, x) = f(t+0.1, x+2) + 2f(t+0.2, x-2) t = range(0, 3; length=101) x = range(-5, 5; length=101) T = u.(t', x) surface(t, x, T; colorbar=false, xlabel="t", ylabel="x", zlabel="T", camera=(30, 70), color=reve…

Hello Thanks for sharing the examples. But when I am trying to run this code I am finding this errors please help me to clear them [Capture]

using LinearAlgebra, SparseArrays, Plots, DifferentialEquations using Surrogates using Plots gr() L=20 N=100 k=50 x=range(0, stop=100, length=100); dx=x[2]-x[1]; dt=0.5*dx^2/(2*k); t=0:dt:10 # print("the vlues of t",t) T=zeros(length(t),length(x)) s=size(T) print("size of matrix",s) T[1,2]=T[1,1]=10…

I’m using Windows 10, and the output of the following code is VERSION = v"1.6.2" Status `D:\.julia\environments\v1.6\Project.toml` [91a5bcdd] Plots v1.20.1 Status `D:\.julia\environments\v1.6\Manifest.toml` [28b8d3ca] GR v0.58.1 Code: @show VERSION using Pkg Pkg.status("Plots") Pk…

VERSION = v"1.6.0" Status `C:\Users\manis\.julia\environments\v1.6\Project.toml` [91a5bcdd] Plots v1.20.0 `https://github.com/JuliaPlots/Plots.jl.git#master` Status `C:\Users\manis\.julia\environments\v1.6\Manifest.toml` [28b8d3ca] GR v0.57.4 I too have the same version

Corrected version of your code: #using LinearAlgebra, SparseArrays, Plots, DifferentialEquations #using Surrogates using Plots #gr() L=20 N=100 k=50 x=range(0, stop=100, length=100); dx=x[2]-x[1]; dt=0.5*dx^2/(2*k); t=0:dt:10 # print("the vlues of t",t) #T=zeros(length(t),length(x)) T=zeros(length(…

[image] genkuroki: @. T[:, 1] = exp(-(x-50)^2/(2*5^2)) # initial values Can you please explain me this line. I havent understood this one as I am new to the Julia

To discover what a symbol means you can type a ? in the REPL. This will get you into the help mode of the RPEL. Once you are in there, you can type the symbol you want to undersantd and click enter. doing ? @. enter gives me: @. expr Convert every function call or operator in expr into a "dot c…

Under the condition T=zeros(length(x),length(t)), the code @. T[:, 1] = exp(-(x-50)^2/(2*5^2)) is equivalent to the following for loop: for i in eachindex(x) T[i, 1] = exp(-(x[i]-50)^2/(2*5^2)) end Code for verification: using Plots k = 50 x = range(0, 100; length=100); dx = step(x) dt = 0.5…
