Data Overview:
11. List data files.
(a) Kronecker.m
(b) NT.m
(c) NTAlgorithm.m
(d) NTAlgorithm2.m
(e) RandOrthMat.m
(f) SolLE.m
(g) smat.m
(h) svec.m
(i) Symmetrization.m
(j) unitvector.m
(k) mainprogram_Ver2.m
(l) mainprogramoutputwithoutsecondordercorrectorwithtime.txt
(m) testprogram_Ver2.m
(n) testprogramoutputwithoutsecondordercorrectorwithtime.txt

12. Explain any relationships between files.
Matlab function files (a), (b), (e)-(j) are used by Matlab script files (k), (m).  Matlab function file (c) is used only by file (k), while Matlab function file (d) is used only by file (m).  File (l) is an output file upon running file (k), while file (n) is an output file upon running file (m).

13. For each file:
i) Description of content
Matlab script file (k) is used to solve randomly generated semi-definite linear complementarity problems;  Matlab script file (m) is used to solve the example provided in Section 5 of the associated paper to the dataset.
ii) If not embedded within the file(s) provide variable metadata, missing data data definitions etc.
NIL
iii) Details of any specialised formats or abbreviations
NIL

Methodological Information:
14. Link to methodology description / or brief description of method.
Dataset is linked to the implementation of the interior point algorithm in the associated paper.  

15. Describe any quality assurance procedures.
NIL

16. Any specific information required to interpret/use use the data e.g. specific instrumentation/software information.
Need Matlab to run script files.
