Week01¶
numerical and analytical are close → approximation → we need to consider the error bar
through different way;however, we want the same answer.
we have to consider how meaningful about analytical sol. → errors
- round off error
- finite digits
- truncation error
- decide the stopping point
certain digits + estimated digit(half of the smallest scale)
accuracy v.s. precision
error definition → percent relative error
$0.5 * 10 ^ {(2 - n)}$ (n is the runTimes)
