## Relative Error Function In Matlab

However, I cannot figure out how to evaluate the error at more than one value for \$h\$ at a time, if there is a way. Therefore, the computer representations always have a truncation error. True Relative Error Formula a series expansion or infinite decimal or underflow. Matlab Absolute Error Messages are exchanged and managed using open-standard protocols.

Perhaps you could generate the approximations of \$f'(0)\$ using the following code: x0 = 0; n = 1000; h = logspace(-16, -1, n); % Generates n numbers logarithmically spaced between 10^(-16)

Instead you could use a log-log plot, loglog(h, err), which shows the absolute error as a function of \$h\$ much more clearly (on a log-log scale). –Kyle Oct 23 '13 at
