% Create the mesh [x, y] = meshgrid(linspace(0, Lx, N+1), linspace(0, Ly, N+1)); % Thermal conductivity Q = 5.0
: High-performance computing (HPC) tasks where execution speed is critical but you still want the ease of MATLAB for data analysis. 4. Official MathWorks Tools: Partial Differential Equation Toolbox While many users prefer custom scripts, the official PDE Toolbox has become significantly more powerful in recent years.
