UNIFORM_DATASET
Generate Uniform Random Datasets

UNIFORM_DATASET is a MATLAB program which creates a uniform random dataset and writes it to a file.

The program allows the user to choose:

• M, the spatial dimension;
• N, the number of points to generate;
• SEED, the initial seed value.

Related Data and Programs:

TABLE is the format used for the output files created by UNIFORM_DATASET.

TABLE_DISCREPANCY is an executable C++ program which can read a TABLE file of points (presumed to lie in the unit hypercube) and compute bounds on the star discrepancy, a measure of dispersion.

UNIFORM is a MATLAB library containing routines which can be used to generate uniform pseudorandom numbers.

UNIFORM is a dataset directory which contains sample datasets created by UNIFORM_DATASET.

UNIFORM_DATASET is also available in a C++ version and a FORTRAN90 version.
