FILTER_RAMP_TRANSITIONS Creates a transition mask for ramp reserves. MD = FILTER_RAMP_TRANSITIONS(MD0, THRESHOLD) Creates a transition mask for ramping reserves, including only transitions with probabilities greater than or equal to a given THRESHOLD value, where the probability of the transition from j1 to j2 is taken to be the conditional probability in TransMat multiplied by the conditional probability of being in state j1, given that you've made it to period t.
