How can I save outputs in a matrix?

r = 0.6 ;
a = @(h) ((pi .* h) .* (3 .* r.^2 - h.^2)) ./ 3 ;
b = @(h) pi .* 0.6^2 .* (h-0.6) ;
c = @(h) pi.*(1/3).*(r.^2 + r.*(3/4).*(0.8-(h-2)) + ((3/4) .* (0.8-(h-2)).^2)) .* (h-2) ;
V = [];
A = a(0.6) ;
B = b(2) ;
h = 0 : 0.1 : 2.8 ;
for i = 0:0.1:2.8;
  if h<=0.6
    V=a(i)
  elseif 0.6<h<=2
    V=A + b(i)
  else 2.0<h<=2.8
    V=A+B+c(i)
  end
end

I wanna make a matrix of V

hvals = 0:0.1:2.8;
for hidx = 1 : length(hvals);
  h = hvals(iidx);
  if h<=0.6
    V(hidx) = a(h);
  elseif 0.6<h & h<=2
    V(hidx) = A + b(h);
  else
    V(hidx) = A + B + c(h);
  end
end
