## Main Question or Discussion Point

Hey, I have defined

and written the loop:

line 38-40

and I get the error

Code:

```
pu = zeros(nx,ny,N);
pv = zeros(nx,ny,N);
pu(:,ny,:) = 1;
```

line 38-40

Code:

```
for i = 2:(nx-1);
for i = 2:(ny-1);
ps(i,j) = p(i,j,n) - a1*(pu(i+1,j,n) - pu(i,j,n)) -a2*(pv(i,j+1,n) - pv(i,j,n));
```

Could someone help me with the error???? Attempted to access pv(2,11,1); index out of bounds because size(pv)=[10,10,10].

Error in ==> fluidmekanikk at 40

ps(i,j) = p(i,j,n) - a1*(pu(i+1,j,n) - pu(i,j,n)) -a2*(pv(i,j+1,n) - pv(i,j,n));
