Matrix dimensions must agree.
Error in ==> g261x05 at 11
Z=(n*R*y/(x-b))-((n.^2)*a)/(x.^2)
when I try and run:
n=1.5; a=1.39; b=0.03913; R=0.08206
y=[273:.1:473];
x=[.3:.1:1.2];
[X,Y]=meshgrid(x,y);
Z=(n*R*y/(x-b))-((n.^2)*a)/(x.^2)
surf(X,Y,Z)
xlabel('Volume (L)');
ylabel('Temperature (K)');
zlabel('Pressure (atm)')
Please help!
It's g285x07 in Gilat if you have the book.
Thanks
