I am a new user of Mathematica, and I am having a little difficulty grasping
the syntax. I am trying to generate a matrix of 0's and 1's given by a
Bernoulli probability distribution. If we look at a case for a matrix with
five different probabilities, x={0.05,0.09,.15,.23,.47}. I have been able
to construct a matrix with these probabilities, but what I cannot do is
reset the probabilites back to the start of the list when a 1 was the last
result in the table. In other words, each time a random Bernoulli generates
a 1, I want the probability for the next xi in the row to be 0.05 again and
continue to preoceed down the list again until another 1 is reached. If
anyone could provide me with some help on the proper syntax for resetting
the probability at the start of the list {x}after a 1 is reached in the row,
I would be grateful.
