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.
