Bug ID: 24969
Summary: Functions to support manipulation of matrices
Product: XPath / XQuery / XSLT
Version: Working drafts
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P2
Component: Requirements for Future Versions
Assignee: jim.melton@acm.org
Reporter: andrew_coleman@uk.ibm.com
QA Contact: public-qt-comments@w3.org
XPath/XQuery 3.0 added support for arrays, including functions to create and
manipulate them. A future version should consider adding functions to support
matrix operations.
Typical operations would be:
- creating n x m matrix (2-dimensional array)
- submatrix (splitting)
- transpose
- matrix addition
- matric multiplication
- scalar operations (addition/subtraction/multiplication etc of each entry)
A few use cases:
- representing graphs (edges, adjacency etc)
- computer graphics (4x4 transformation matrix representing translation,
rotation, scaling, perspective/orthogonal projection)
- data structures for probability and statistics
- linear algebra
