Method Detail

haltonSeq

public static DblMatrix haltonSeq(int NUMPTS,
                  int[] PRIMES)

Returns a matrix representing P.length separate Halton sequences each having NUMPTS entries. The output matrix has NUMPTS rows and P.length colums. P is expected to contain distinct prime numbers.

haltonSeq

public static DblMatrix haltonSeq(int NUMPTS,
                  int NDIMS)

Returns a matrix representing NDIMS separate Halton sequences each having NUMPTS entries. The output matrix has NUMPTS rows and NDIMS colums.

haltonSeq

public static DblMatrix haltonSeq(int[] INDICES,
                  int NDIMS)

Returns a matrix representing NDIMS separate Halton sequences each having only the sequence indices indicated. The output matrix has INDICES.length rows and NDIMS colums.
