It seems to me that you are typesetting matrices here. Note that amsmath provides matrix environments (matrix, pmatrix, bmatrix, etc…), so that you do not need to type your own delimiters around an array. (You would want bmatrix.) To get augmented matrices, use the code from the question: How does this macro for augmented matrices work? Edit: Included ...

One possibility, is to tackle the problem in the other sense: instead of shortening the dashed line, you can enlarge the delimiters: \documentclass[a4paper]{article} \usepackage{arydshln} \usepackage{mathtools} \begin{document} \begin{equation*} \delimitershortfall=0pt \setlength{\dashlinegap}{2pt} \left[\begin{array}{cccc:c} a_{11} & a_{12} & ...

You need to enclose the pmatrix environment in a pair of braces { } The internal version of \Aboxed, \@Aboxed, uses & to split its argument. Normally, this just strips everything after a possible second &, as in the second example below. In this case though, you’re splitting the pmatrix environment which would create a sequence of math-mode commands ...

You can do it like this, provided your main matrix has no unusually big objects (otherwise you can play with the first argument to \dottedcolumn that also accepts decimal numbers). \documentclass{article} \usepackage{amsmath} \newcommand{\dottedcolumn}[3]{% \settowidth{\dimen0}{$#1$} \settowidth{\dimen2}{$#2$} \ifdim\dimen2>\dimen0 \dimen0=\dimen2 ...

Taking some code from How to get a good "divisible by" symbol?, you can create your own \vdots that has any number of predefined dots. Here I've defined \sixvdots: \documentclass{article} \usepackage{amsmath}% http://ctan.org/pkg/amsmath \newcommand{\sixvdots}{% \vbox{\baselineskip1ex\lineskiplimit0pt% ...

One of the reasons why I always use (square) brackets for delimiting matrices is that the larger the matrices are, the fatter the parentheses become. Compare the two results, one with pmatrix, the other with bmatrix: The parentheses don't add to clarity, only to the required space. One might argue that the "T" is too far also in the second case, but I ...

no vertical lines, no centering, friendlier spacing: \documentclass[12pt]{article} \usepackage{booktabs,leading} \usepackage[utf8]{inputenc} \usepackage[justification=raggedright,singlelinecheck=false]{caption} \begin{document} \begin{table} \leading{16pt} \caption{\label{tab2} FMM: profiling of subroutines} \begin{tabular}{llllllll} ...

Don't use vertical lines at all: \documentclass[a4paper,12pt]{article} \usepackage{amsmath, amsmath, amssymb} \usepackage{caption} \usepackage{ctable} \usepackage{multirow} \begin{document} \begin{table}[H]\centering \caption{\label{tab2} FMM: profiling of subroutines} \begin{tabular}{lcccccc}\FL \multirow{2}{*}{$\Theta$} & ...
