printMatrix

Print a matrix, allowing fractions or LaTeX output

A collection of matrix functions for teaching and learning matrix
linear algebra as used in multivariate statistical methods. These functions are
mainly for tutorial purposes in learning matrix algebra ideas using R. In some
cases, functions are provided for concepts available elsewhere in R, but where
the function call or name is not obvious. In other cases, functions are provided
to show or demonstrate an algorithm. In addition, a collection of functions are
provided for drawing vector diagrams in 2D and 3D.

printMatrix function

<dl><dt>A</dt>
<dd>A numeric matrix</dd>
<dt>parent</dt>
<dd>flag used to search in the parent envir for suitable definitions of other arguments.
Set to <code>TRUE</code> (the default) if you want to only use the inputs provided.</dd>
<dt>fractions</dt>
<dd>If <code>TRUE</code>, print numbers as rational fractions, using the <code><a href="/link/fractions?package=matlib&version=0.9.8" data-mini-rdoc="matlib::fractions">fractions</a></code>
function; if you require greater accuracy, you can set the <code>cycles</code> (default 10)
and/or <code>max.denominator</code> (default 2000) arguments to <code>fractions</code> as a global option, e.g.,
<code>options(fractions=list(cycles=100, max.denominator=10^4))</code>.</dd>
<dt>latex</dt>
<dd>If <code>TRUE</code>, print the matrix in LaTeX format</dd>
<dt>tol</dt>
<dd>Tolerance for rounding small numbers to 0</dd></dl>
