 The `matlib` package extends these, providing a collection of functions that simplify using LaTeX notation for matrices, vectors and equations in documentation and in writing:
 
 * `latexMatrix()`: Constructs the LaTeX code for a symbolic matrix, whose elements are a symbol, with row and column subscripts. `latexMatrix()` also supports matrices with numeric elements, and the objects it produces may be used in various kinds of matrix computations, both symbolic and numeric.
-* `matrix2latex()`: Constructs the LaTeX code for a symbolic matrix, whose elements are a symbol, with row and column subscripts
+* `Eqn()`: A wrapper to produce LaTeX expressions or equations that can be used directly in `.Rmd` or `.qmd` documents to compile to equations. It also provides for direct preview of the resulting equation.
 * `showEqn()`: Shows what matrices $\mathbf{A}, \mathbf{b}$ look like as the system of linear equations, $\mathbf{A x} = \mathbf{b}$, but written out as a set of equations.
-* `Eqn()`: A wrapper to produce LaTeX expressions or equations that can be copied/pasted into documents or used directly in `.Rmd` or `.qmd` documents to compile to equations.
 
 When used directly in R, these functions produce their output to the console (using `cat()`).
 In a `.Rmd` or `.qmd` document, use the chunk options: `results='asis', echo=FALSE`
 so that `knitr` just outputs the text of the equations to the document.
