If your process is just to sample until you are within a tolerance of V_1 and you want things to be truly random, how about the following algorithm: Randomly shuffle the entries of V Take a cumulative sum If th
Example:s = RandStream('mlfg6331_64')creates a random number stream that uses the multiplicative lagged Fibonacci generator algorithm. Output Arguments collapse all Sample, returned as a vector or scalar. Ifk = 1, thenyis a scalar. Ifk > 1, thenyis ak-by-1 vector. ...
