I assume the goal is to have the Latex output close to the screen output in Maple. In these examples this is the case.

**Example 1**

restart; A:=Matrix([[1,-1,0,2],[1,2,2,-2],[0,2,3,-1]]): LinearAlgebra:-NullSpace(A)

But the Latex generated for the above, using the Latex() command is

\{ \left[\begin{array}{c}0 \\2 \\-1 \\1 \end{array}\right] \}

Which when compiled

\documentclass[11pt]{article} \usepackage{amsmath} \begin{document} \[ \{ \left[\begin{array}{c}0 \\2 \\-1 \\1 \end{array}\right] \} \] \end{document}

gives

The latex should instead be

\left\{ \left[\begin{array}{c}0 \\2 \\-1 \\1 \end{array}\right] \right\}

Which compiles to

**Example 2**

restart; A:=Matrix([[1,-1,0,2],[1,2,2,-2],[0,2,3,-1]]): LinearAlgebra:-RowSpace(A)

The Latex of the above is

[\left[\begin{array}{cccc}1 & 0 & 0 & 0 \end{array}\right], \left[\begin{array}{cccc}0 & 1 & 0 & -2 \end{array}\right], \left[\begin{array}{cccc}0 & 0 & 1 & 1 \end{array}\right]]

Which when compiled gives

\documentclass[11pt]{article} \usepackage{amsmath} \begin{document} \[ [\left[\begin{array}{cccc}1 & 0 & 0 & 0 \end{array}\right], \left[\begin{array}{cccc}0 & 1 & 0 & -2 \end{array}\right], \left[\begin{array}{cccc}0 & 0 & 1 & 1 \end{array}\right]] \] \end{document}

gives

A better Latex would be

\left[\left[\begin{array}{cccc}1 & 0 & 0 & 0 \end{array}\right], \left[\begin{array}{cccc}0 & 1 & 0 & -2 \end{array}\right], \left[\begin{array}{cccc}0 & 0 & 1 & 1 \end{array}\right]\right]

Which compiles to

Now the size of the [[ is the same on both ends.

**example 3**

restart; A:=Matrix([[1,-1,0,2],[1,2,2,-2],[0,2,3,-1]]): LinearAlgebra:-ColumnSpace(A)

The Latex given for the above is

[\left[\begin{array}{c}1 \\0 \\0 \end{array}\right], \left[\begin{array}{c}0 \\1 \\0 \end{array}\right], \left[\begin{array}{c}0 \\0 \\1 \end{array}\right]]

Which when compiled

\documentclass[11pt]{article} \usepackage{amsmath} \begin{document} \[ [\left[\begin{array}{c}1 \\0 \\0 \end{array}\right], \left[\begin{array}{c}0 \\1 \\0 \end{array}\right], \left[\begin{array}{c}0 \\0 \\1 \end{array}\right]] \] \end{document}

gives

A better Latex is

\left[\left[\begin{array}{c}1 \\0 \\0 \end{array}\right], \left[\begin{array}{c}0 \\1 \\0 \end{array}\right], \left[\begin{array}{c}0 \\0 \\1 \end{array}\right]\right]

Which compiles to
