matrixNew: Generate random/diagonal/zeros/ones Matrix

In paodan/funcTools: some useful function tools in practice

Generate random/diagonal/zeros/ones Matrix

Description

Generate random/diagonal/zeros/ones matrix, the default is 3 by 3 matrix of 0.

Usage

matrixNew(
  m = 3,
  n = NULL,
  x = 0,
  diagonal = FALSE,
  distr = NULL,
  dimnames = NULL
)

Arguments

m	Number of rows.
n	Number of columns. If n = NULL, then n = m.
x	The value filling in the matrix .
diagonal	Logical, only diagonal remains if TRUE
distr	Distribution functions, e.g. rnorm, rt, runif, etc. If distr is provided, then x will be masked.
dimnames	A dimnames attribute for the matrix: NULL or a list of length 2 giving the row and column names, respectively.

Value

A random/diagonal/zeros/ones Matrix.
