Convert matrix or string to LaTeX format

stm_to_latex() converts a matrix or string into LaTeX code for rendering mathematical expressions. Supports optional alignment and decimal rounding.

Usage

stm_to_latex(
  x,
  align = c("right", "center", "left"),
  symbol = "$",
  name = NULL,
  digits = NULL
)

Arguments

x

The matrix, vector, or string to convert to LaTeX format.

align

Optional. The alignment for matrix columns. Choices are "right", "center", or "left". Default is "right".

symbol

Optional. The symbol to wrap around the LaTeX expression. Default is "$".

name

Optional. The name for the equation. If provided, it will appear before the LaTeX code.

digits

Optional. The number of digits to round the matrix elements to. Default is NULL (no rounding).

Value

A LaTeX formatted string.

Details

The function supports both converting a matrix and rendering a string as a LaTeX equation. It also allows custom alignment of matrix columns and rounding of matrix values to the specified number of digits.

Examples

stm_to_latex("x^2 + y^2 - z^2")
#> [1] "$\\displaystyle x ^{2} + y ^{2} - z ^{2}$"
stm_to_latex(matrix(1:4, nrow = 2), align = "center", digits = 2)
#> [1] "$\\left[\\begin{array}{cc} 1 & 3 \\\\ 2 & 4 \\end{array}\\right]$"
stm_to_latex(matrix(1:4, nrow = 2), name = "A")
#> [1] "$A = \\left[\\begin{array}{rr} 1 & 3 \\\\ 2 & 4 \\end{array}\\right]$"
