rowReduce

rowReduce(A, a)

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 \(A x = a\)

Outputs

• 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
