amscd
The amscd extensions implements the CD environment for commutative diagrams. See the AMScd guide for more information on how to use the CD environment.
This extension is loaded automatically when the autoload extension
is used. To load the amscd extension explicitly, add
'[tex]/amscd'
to the load
array of the loader
block of
your MathJax configuration, and add 'amscd'
to the packages
array of the tex
block.
window.MathJax = {
loader: {load: ['[tex]/amscd']},
tex: {packages: {'[+]': ['amscd']}}
};
Alternatively, use \require{amscd}
in a TeX expression to load it
dynamically from within the math on the page, if the require
extension is loaded.
amscd Options
Adding the amscd extension to the packages
array defines an
amscd
sub-block of the tex
configuration block with the
following values:
MathJax = {
tex: {
amscd: {
colspace: '5pt',
rowspace: '5pt',
harrowsize: '2.75em',
varrowsize: '1.75em',
hideHorizontalLabels: false
}
}
};
- colspace: '5pt'
This gives the amount of space to use between columns in the commutative diagram.
- rowspace: '5pt'
This gives the amount of space to use between rows in the commutative diagram.
- harrowsize: '2.75em'
This gives the minimum size for horizontal arrows in the commutative diagram.
- varrowsize: '1.75em'
This gives the minimum size for vertical arrows in the commutative diagram.
- hideHorizontalLabels: false
This determines whether horizontal arrows with labels above or below will use
\smash
in order to hide the height of the labels. (Labels above or below horizontal arrows can cause excess space between rows, so setting this totrue
can improve the look of the diagram.)
amscd Commands
The amscd extension implements the following macros:
