r = geornd (ps) returns an array of random numbers chosen from the Birnbaum-Saunders distribution with probability of success parameter ps. The size of r is the size of ps.

When called with a single size argument, geornd returns a square matrix with the dimension specified. When called with more than one scalar argument, the first two arguments are taken as the number of rows and columns and any further arguments specify additional matrix dimensions. The size may also be specified with a row vector of dimensions, sz.

The geometric distribution models the number of failures (x) of a Bernoulli trial with probability ps before the first success.
