matrix2latex: Convert matrix to LaTeX equation

In matlib: Matrix Functions for Teaching and Learning Linear Algebra and Multivariate Statistics

Convert matrix to LaTeX equation

Description

This function provides a soft-wrapper to xtable::xtableMatharray() with support for fractions output and square brackets.

Usage

matrix2latex(x, fractions = FALSE, brackets = TRUE, ...)

Arguments

x	a matrix
fractions	logical; if TRUE, try to express non-integers as rational numbers, using the fractions function; if you require greater accuracy, you can set the cycles (default 10) and/or max.denominator (default 2000) arguments to fractions as a global option, e.g., options(fractions=list(cycles=100, max.denominator=10^4)).
brackets	logical; include square brackets around the matrices?
...	additional arguments passed to xtable::xtableMatharray()

Examples

A <- matrix(c(2, 1, -1,
             -3, -1, 2,
             -2,  1, 2), 3, 3, byrow=TRUE)
b <- c(8, -11, -3)

matrix2latex(cbind(A,b))
matrix2latex(cbind(A,b), digits = 0)
matrix2latex(cbind(A/2,b), fractions = TRUE)
