Hello,

I have a small problem with an array.

I have an initial array with nx x ny positions, then I create another array with nx x ny positions, but I set only the Boundary values.

Afterward, I would like to merge the inner values from Tini (nx-2 x ny-2 positions, marked with a red rectangle in the picture below) into the inner area of the array T (marked with a blue rectangle in the image below).

nx=6;
ny=6;
Tini=300*ones(nx,ny) 
TL=400; 
TR=800; 
TT=600; 
TB=900; 
T(2:ny-1,1)=TL;
T(2:ny-1,nx)=TR;
T(1,2:nx-1)=TT;
T(ny,2:ny-1)=TB;
T(1,1)=(T(2,1)+T(1,2))/2;
T(nx,ny)=(T(nx-1,ny)+T(nx,ny-1))/2;
T(1,ny)=(T(2,ny)+T(1,ny-1))/2;
T(nx,1)=(T(nx-1,1)+T(nx,2))/2;
