Array indices must be positive integers or logical values.

for i = 1:dt:tEmpty
heightArray(1,i) = sqrt(h1) - (.5 * k .* timesArray(i))^2;
flowRateArray(1,i) = sqrt(2 * g .* heightArray(1,i));
massFlowRateArray(1,i) = exitHoleArea * p .* flowRateArray(1,i);
end
Here is the Error message I am getting.
Array indices must be positive integers or logical values.
Error in Luke_Witherow_hw4>drainTank_Loop (line 53)
heightArray(1,i) = sqrt(h1) - (.5 * k .* timesArray(i))^2;

Try this —
iv = 1:dt:tEmpty;
for i = 1:numel(iv)
heightArray(1,i) = sqrt(h1) - (.5 * k .* timesArray(i))^2;
flowRateArray(1,i) = sqrt(2 * g .* heightArray(1,i));
massFlowRateArray(1,i) = exitHoleArea * p .* flowRateArray(1,i);
end
I am guessing that ‘dt’ is not an integer, and that is throwing the error.
