%Pembagian Grid
xgrid=4;
ygrid=3;
U=(zeros(ygrid+1,xgrid+1));
x=linspace(a,b,xgrid+1);
for i=1:xgrid+1
U(1,i)=sym(sin(pi*x(i)));
end
w=sym('w',[1(xgrid-1)*(ygrid-1)]);
k=1;
for j=2:ygrid
for i=2:xgrid
U(j,i)=w(k);
k=k+1;
end
end
error Unbalanced or unexpected parenthesis or bracket in "w=sym('w',[1(xgrid-1)*(ygrid-1)]);"
