Dear all

I was successfully able to generate and run 1D-shocktube code in MATLAB. Now I am trying to extend the same to 2D but I am facing some difficulty here.

Whenever I try to run the 2D code I am getting the following error "
*"Array dimensions must match for binary array op.

Error in laxfried1 (line 45)
w(:,2:nx-1,2:ny-1)=((w(:,3:nx,2:ny-1)+w(:,1:nx-2,2:ny-1)+w(:,2:nx-1,3:ny)+w(:,2:nx-1,1:ny-2))/4)-(dt/(2*dx)).*(F(:,3:nx,2:ny-1)-F(:,1:nx-2,2:ny-1))-..."*

Can anyone help me out where i went wrong, I am trying from my side as well. Please find attached 1D and 2D code for your reference. Thank you all.
