<mmultiscripts>
The MathML <mmultiscripts>
element allows you to create tensor-like objects. In a descriptive way tensors are multidimensional matrices (mathematical imprecise but exemplified). The degree of a tensor depends on the dimensionality of a representative array. For example, a number is a 0-dimensional array, or a 0th-order tensor. A 1-dimensional array (e.g. vectors) is a 1st-order tensor and so 2nd-order tensors are needed to represent square matrices. To learn more about the mathematical background of tensors refer to the entry on Wikipedia.
MathML uses a special syntax to describe subscripts and superscripts for both, postscripts and prescripts, attached to a base expression:
<mmultiscripts>
base
(subscript superscript)*
[ <mprescripts/> (presubscript presuperscript)* ]
</mmultiscripts>
After the base expression you can specify a postsubscript and a postsuperscript. Prescripts are optional and are separated by the empty tag <mprescripts/>
(only one <mprescripts /> element is allowed, otherwise you will get an DuplicateMprescripts
error in the Error Console and "invalid-markup" in your rendering). In addition you are able to use <none/>
as a placeholder for empty scripts (not for the base). See the examples section for a correct usage.
Attributes

-
Provided for use with stylesheets.
displaystyle
-
A Boolean value specifying whether more vertical space is used for displayed equations or, if set to
false
, a more compact layout is used to display formulas. The main effect is that larger versions of operators are displayed, whendisplaystyle
is set totrue
. See alsomovablelimits

-
Used to set a hyperlink to a specified URI.
mathbackground
-
The background color. You can use
#rgb

and HTML color names. mathcolor
-
The text color. You can use
#rgb
,#rrggbb
and HTML color names. subscriptshift
-
The minimum space by which to shift the subscript below the baseline of the expression, as a CSS length. This property is deprecated and will be removed in the future.
superscriptshift
-
The minimum space by which to shift the superscript above the baseline of the expression, as a CSS length. This property is deprecated and will be removed in the future.
