Random Matrix Generator
The software are developed in MATALB® on Windows and Linux platforms. Please download and install the appropriate Matlab Compiler Runtime (MCR) as well.
The software sythesizes random realizations of low-rank and sparse matrices of specified types.
These software is used in, and the matrix constructions details can be found in .
Input arguments: LS typ n frs reps fname
LS: specify either low-rank or sparse. Use L or l to indicate low-rank matrices, and S or s to indicate sparse matrices.
typ: indicates the type of the matrices. Types available for low-rank are:
Type available for sparse matrices are:
- First order Gaussian
- Second order Gaussian
- First order Vandermonde
- Second order Vandermonde
n: size of the matrices.
frs: fractional rank or fractional sparsity of the matrix.
reps: number of realizations of the specified matrix.
fname: base file name of the matrices. reps many files will be produced each containing a comma-delimited realization of the specified matrix. E.g.: If fname is testfile and reps is 3, then three output files with names testfile.1, testfile.2, and testfile.3 will be produced.
DOS: genRandMats-1.0.exe L 1 20 0.1 3 testfile
Linux: ./run_genRandMatix_v01a.sh $MCR_DIRECTORY L 1 20 0.1 3 testfile
