Method Details

map_sample

public static double[] map_sample(MatrixCell MAP,
 long n,
 Random random)

Generates samples of inter-arrival times from a MAP using a specified number of samples and a random generator.

Parameters:

MAP - the MatrixCell representing the MAP, containing the D0 and D1 matrices

n - the number of samples to generate

random - the random number generator to use

Returns:

an array of doubles containing the generated samples

map_sample

public static double[] map_sample(Matrix D0,
 Matrix D1,
 long n,
 Random random)

Generates samples of inter-arrival times from a MAP using a specified number of samples and a random generator.

Parameters:

D0 - the hidden transition matrix of the MAP

D1 - the visible transition matrix of the MAP

n - the number of samples to generate

random - the random number generator to use

Returns:

an array of doubles containing the generated samples

map_sample

public static double[] map_sample(Matrix D0,
 Matrix D1,
 long n,
 Random random,
 PhaseTrace trace)

As map_sample(Matrix, Matrix, long, Random), additionally recording the CTMC sojourns of the walk into trace (cleared first; when n > 1 the sojourns of all samples are concatenated). The random draws, their order and the returned samples are identical to the non-recording call: recording reads the walk, it never drives it.

Parameters:

trace - sojourn recorder, or null to record nothing

bmap_sample

public static BmapSample[] bmap_sample(MatrixCell bmap,
 long n,
 Random random)

Generates samples from a BMAP (Batch Markovian Arrival Process).

bmap_sample

public static BmapSample[] bmap_sample(Matrix D0,
 Matrix D1_total,
 Matrix[] Dk,
 long n,
 Random random)

Generates samples from a BMAP using D0, D1_total, and individual Dk matrices.
