我正在编写此功能。运行函数时出现此错误
分配比非单例下标具有更多非单例rhs维度。 我无法理解错误在哪里。
Lx = r;
Ly = z;
Nx = 20;
Ny = Nx;
dx = Lx/Nx;
dy = Ly/Ny;
k = 0.72;
rho = 1920; % Density (kg/m^3)
Cp = 835; % Specific heat (J/kgK)
alpha = k/(rho*Cp); % Thermal diffusivity (m^2/s)
deltaT = 1300; % Time step (seconds)
deltaT_stable_max = .25*dx.^2/alpha; % Maximum stable time step
Fo = alpha*deltaT./dx.^2; % Fourier number
T=(21:0.1:35)
T1 = T; % BC temperature 1 (deg. Celsius)
T2(1) = T(1); % BC temperature 2 (deg. Celsius)
T = T1 %.*ones(Nx+1,Ny+1); % Initialize T array to T1 everywhere
T(1:Nx,Ny+1) = T2; % Initialize top row to T2 boundary condition
T(1,Ny+1) = T2; % Initialize top left
T(Nx+1,Ny+1) = T2; % Initialize top right
Tplot = ones(Lmax,1); % Initialize Tplot to allocate memory
x = 0:dx:Lx; % Create x-distance node locations
y = 0:dy:Ly; % Create y-distance node locations
for L = 1:Lmax % Loop through time steps
Told = T; % Store previous T array as Told for next time step
for j = 2:length(h) % Loop through rows
for i = 2:length(h) % Loop through columns
T2(i,j) = Fo*(Told(i-1,j) + Told(i+1,j) + Told(i,j-1)+ Told(i,j+1)) + (1-4*Fo)*Told(i,j);
end
end
end
谢谢
