However for matrices operations perhaps it could be better to have also some little commands or helps, like a command to extract pivots, to get cofactors, adjoint, minors, and also factorizations LDU (LDV) and LDLt. As they are missing, I'm trying to make some programs, but for pivots I'm getting these troubles... Some other calculators have those commands, if I well remember (i.e., TI 89/Voyage had adj / cofactor function)... For example I use a lot a little program to get minor of a matrix: Code:
I made a program to calculate Cofactor matrix and adjoint matrix (see here)... Salvo ∫aL√0mic (IT9CLU) :: HP Prime 50g 41CX 71b 42s 39s 35s 12C 15C  DM42, DM41X  WP34s Prime Soft. Lib
