Dimension Mismatch in loop, for some values the amount of iterations does not equal the dimensions of the matrix of outputted valued (eg. V = 300 D = 5)

V = input('Input Volume\n'); D = input('Input Diameter\n');

A = ((D/2)^2)*pi; %Area H = V/A; %Height g = 9.81; %Gravity

y = [H:-0.1:0];

v = 1;

for i = H:-0.1:0 VELOCITY = sqrt(2*g*i); x(v) = VELOCITY; v =v+1;

end

plot(x,y) title('Velocity vs. Height in Tornicelli''s Law') xlabel('Velocity (meters per second)') ylabel('Height (meters)')

I did not receive an error while running this script. Can you explain the problem?

I figured out the problem, because I ran it multiple times without clearing the workspace first some values caused the error

Okay then.
