How to draw a nice diagonal matrix?
How to typeset a nice looking diagonal matrix? I find myself, once again, fiddling with phantoms and running raiseboxes to get an aesthetic result. This kind of micromanagement is bad practice, but why does the default look so bad and is there a better way? 
documentclass{article}
usepackage{mathtools}
begin{document}
begin{align*}
operatorname{diag} x &=
begin{bmatrix}
x_1 & 0 & 0\
0 & ddots & 0 \
0 & 0 & x_n
end{bmatrix}
&
operatorname{diag} x &=
begin{bmatrix}
x_1 & 0 & 0\
0 & raisebox{-0.4ex}{(ddots)}rule[3.4ex]{0pt}{0pt} & 0 \
0 & 0 & x_n rule[3.4ex]{0pt}{0pt}
end{bmatrix}

First, useDeclareMathOperatorif you use "diag" many times in the document.

A TABstack alternative.
documentclass{article}
usepackage{mathtools,tabstackengine}
TABstackMath% STACK MATRIX IN MATH MODE
setstacktabbedgap{10pt}% INTER-COLUMN GAP SIZE
setstackgap{L}{1.5baselineskip}% INTER-ROW BASELINESKIP
newcommandcddots{raisebox{-1pt}{$ddots$}}
begin{document}
[ operatorname{diag} x =
bracketMatrixstack{
x_1 & 0 & 0\
0 & cddots & 0 \
0 & 0 & x_n
}
]
end{document}
While not needed for diagonal matrices of the type portrayed by the OP, the package has a fixTABwidth{<T or F>} declaration to fix all column widths to the largest found in the matrix. That can be helpful if there are wide matrix entries:
