Hello HP 50g friends,
I watched a strange behavier of the RREF command.
If I input the matrix:
and use the RREF command, I get:
That is something else as aspected, but if I use a second time RREF I get the aspected form of the matrix:
Is there anybody who can explain me the strange behavier? It is not a question of the calculation mode (approxmative or exact)?
Thank you in advance,
sincerely peaceglue
I watched a strange behavier of the RREF command.
If I input the matrix:
Code:
[[ 7.6440528636 7.6440528636 -300. -53.1753303963 ]
[ -10.192070485 -10.192070485 0. 229.289735683 ]
[ 61.847 0 0. 8. ]]
and use the RREF command, I get:
Code:
[[ 1. 0. 0. .129351464097 ]
[ 1. 1.0192070485E14 0. -2.30608094922E15 ]
[ 1. -.15384615385 4.61538461549E15 -1.82756879024E15 ]]
That is something else as aspected, but if I use a second time RREF I get the aspected form of the matrix:
Code:
[[ 1. 0. 0. 0. ]
[ 0. 1. 0. -22.6262264632 ]
[ 0. 0. 1. -.395973237876 ]]
Is there anybody who can explain me the strange behavier? It is not a question of the calculation mode (approxmative or exact)?
