Permutation Vectors with lu, luinc, ldl
Permutation vectors for lu, luinc, and ldl provide memory savings and, for large data, a
noticeable performance improvement. You can now store permutation information in a
single 1-by-N vector instead of an n-by-n matrix,
Two-Element Threshold for lu, spparms
A new two-element threshold for lu and spparms gives you more control over sparse lu
and sparse \ behavior.
Lower Triangular Factors from symbfact
Extra arguments exported for symbfact allow the return of the lower triangular symbolic
factor.
