RMAT is an R package for simulating random matrices and ensembles as well as computing and analyzing their eigenvalue spectra and dispersions.
NOTE: This package has been submitted to CRAN and is pending release.
You can install the package in one of two ways:
# Through CRAN
install.packages("RMAT")
# Through Github
devtools::install_github(repo = "ataqi23/RMAT")The package can be thought to contain two priamry modules: the matrix module and spectral statistics module.
Included in the package are various wrapper functions for generating
random matrices very efficiently. They follow the RM_xxx
format in allusion to the stats sampling functions like
rnorm. Every matrix sampling function has an ensemble
counterpart in the RME_xxx format.
Consider the following example:
library(RMAT)
# Generate an ensemble of 50x50 Complex Hermitian Standard Normal matrices
ens <- RME_norm(N = 20, cplx = T, herm = T, size = 50)The matrices included are:
The two primary functions in the spectral statistics module are
spectrum and dispersion. These two functions
take either a matrix or an ensemble, and return the respective
eigenvalue spectrum or dispersion. Consider the following example:
library(RMAT)
# Generate a random matrix ensemble
ens <- RME_beta(N = 20, beta = 4, size = 50)
# Compute the spectral statistics of the ensemble
ens_spectrum <- spectrum(ens, sort_norms = FALSE)
ens_dispersion <- dispersion(ens, pairs = "consecutive", sort_norms = FALSE)This package was developed as a part of my Reed senior thesis in the Spring of 2021.
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
