nx = 100; % number of spatial nodes nt = 500; % number of time steps dx = l / (nx - 1); % spatial grid size dt = 0.001; % time step in matlab

To create a grid of spatial nodes and time steps in MATLAB, you can use the following code:

main.m
nx = 100;        % number of spatial nodes
nt = 500;        % number of time steps
l = 1;           % length of the grid
dx = l / (nx - 1); % spatial grid size
dt = 0.001;       % time step

In this code, nx represents the number of spatial nodes, nt represents the number of time steps, l represents the length of the grid, dx represents the spatial grid size, and dt represents the time step. By adjusting these variables, you can control the resolution and duration of your simulation.
