Rowreduce

rowReduce(A, a, mode, printLevel)

Eliminates dependent rows from A & a where \(A x = a\)

USAGE

[AA, aa, pp, rankA, p] = rowReduce (A, a)

INPUT

A – from \(A x = a\)

OPTIONAL INPUT

• a – from \(A x = a\)

• mode – If mode=1, LUSOL operates on A itself. If mode=2, LUSOL operates on A’.

• printLevel

OUTPUT

• AA – row reduced A

• aa – row reduced a i.e. aa = a(pp)

• pp – 1:rankA indices of independent rows

• rankA – rank of A

• p – row permutation which leaves first 1:rankA rows independent and last rows dependent
