You have some control over the step distance used for finite differencing operations (through FiniteDifferenceStepSize), and for the active-set algorithm, you can bound the size of the steps taken from 
to 
using RelLineSrchBnd and RelLineSrchBndDuration. However, there is no parameter that lets you dictate, in absolute terms, the size of the steps taken from to . Not all fmincon algorithms even have a stepping mechanism where such a thing would make sense.
