MAT C=#SAMPLE(A,m,<SRS|URS>,<rand>)
makes a random sample of size m from rows of matrix A
using random number generator <rand>.
The sample is saved as a matrix file C.
By SRS a Simple Random Sample (i.e. without replacement) and
by URS a Unrestricted Random Sample (i.e. with replacement)
is generated.
MAT C=#SAMPLE(A,m,n,<SRS|URS>,<rand>)
works similarly but makes n samples of size m from rows of A
as a matrix C with m*n rows.
