I have the following code that generates a 0 or a 1 depending on the probability p:
randsample([0 1],1,true,[1 - p p])
But suppose my probability was taken from a vector of other probabilities. Is it possible to ammend my code to handle all probabilities at once, rather than looping through the vector for each probability?

I don't understand your question, nor do I have the toolbox for this function, so I can't play around with it for you.

p in the code is a single value. I am asking if this function can handle multiple values of p at once, thus generating a vector of 0's and 1's corresponding to a vector of p values.

double( rand(size(p)) < p )

Assuming yoy have p in a vector
r = rand(size(p))<p
