The toolbox is excellent, though the "null" and "nullt" functions are not working in some cases -> they can return a basis with 1 vector when nullity is 2. I think (not 100% sure) I found a way to correct it, and is to change the nullt function to the following:
(a)
Func
Local nty, cola
colDim(a)→cola
toolbox\nullity(a)→nty
If nty=0:Return "Nonexistent"
augment(a,identity(rowDim(a)))→a
Return (subMat(ref(a),cola+1-nty,colDim(a)-rowDim(a)+1))T
EndFunc
