Following code is coming up with error "Array indices must be positive integers or logical values."
Does someone know what is causing this. Trying to store each value into an array
z =@(x) tan(x);
h = 0.5
for x=1:0.5:10
Output (x) = (z(x+h)-z(x-h))/(2*h);
end
Array = [Output]

z =@(x) tan(x);
h = 0.5
x=1:0.5:10
Output = zeros(1,19) %preallocation for speed and efficiency
for i = 1:numel(x)
Output (i) = (z(x(i)+h)-z(x(i)-h))/(2*h);
end
Array = Output

@madhan ravi: where is the array preallocation? What do those square brackets do? (Hint: nothing)
