In the lookup table blocks in Simulink there is the option to clip rather than extrapolate, when this option is selected the option "Use last table value for inputs at or above last breakpoint" appears. What is the purpose of this option? I looked at the documentation and and the way it is described the block should use the end breakpoint value regardless of whether the box is checked (bp(end) with f = 0 or bp(end-1) with f = 1 result in the same value). I also did a simulation and the output of the lookup with input exceeding the last breakpoint is the same to long precision with or without this box checked.
