UNIFORM_DATASET
Generate Uniform Random Datasets

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

Usage:

r = uniform_dataset ( m, n, seed )

• m is the spatial dimension;
• n is the number of points to generate;
• seed is the initial seed value.
• r is the computed m by n dataset.
