Also for “Eigenvalues()” , I tried as follows:

################################################

\$ export MapleCommand2="with(LinearAlgebra): M:=<<-1,-3,-6>|<3,5,6>|<-3,-3,-4>>: seq( ifelse(Equal( <2,2,-4> , Eigenvalues(M) ),1,0) , k=1..5);"

\$ for i in {1..3} ; do echo " \$MapleCommand2" | maple -sq ; done;
0, 0, 0, 0, 0
0, 0, 0, 0, 0
0, 0, 0, 0, 0

\$ for i in {1..3} ; do echo "randomize(1): \$MapleCommand2" | maple -sq ; done;
0, 0, 0, 0, 0
0, 0, 0, 0, 0
0, 0, 0, 0, 0

\$ for i in {1..3} ; do echo "randomize(2): \$MapleCommand2" | maple -sq ; done;
0, 0, 0, 0, 0
0, 0, 0, 0, 0
0, 0, 0, 0, 0

Even(?) randomize() command cannot control the order. I tried as follows:

################################################

\$ export MapleCommand="with(LinearAlgebra): M:=<<-1,-3,-6>|<3,5,6>|<-3,-3,-4>>: seq( ifelse(Equal( <2,2,-4> , op(1, [Eigenvectors(M)] )),1,0) , k=1..5);"

\$ for i in {1..3} ; do echo "\$MapleCommand" | maple -sq ; done;
1, 0, 0, 0, 1
1, 0, 0, 0, 0
0, 1, 1, 1, 1

\$ for i in {1..3} ; do echo "randomize(1): \$MapleCommand" | maple -sq ; done;
0, 1, 0, 0, 1
0, 1, 1, 1, 1
0, 1, 1, 0, 0

\$ for i in {1..3} ; do echo "randomize(2): \$MapleCommand" | maple -sq ; done;
1, 0, 0, 0, 1
0, 0, 1, 1, 1
0, 1, 1, 1, 0

I have a related(?) question.

What about the randomness of the following orders ?

> with(LinearAlgebra):

> M:=<<-1,-3,-6>|<3,5,6>|<-3,-3,-4>>:

> for k from 1 to 4 do Transpose(op(1, [Eigenvectors(M)] )); end do;

[2, 2, -4]

[-4, 2, 2]

[2, 2, -4]

[2, 2, -4]

I think it is important for you to present  your own ideas to attack your problems.

What is NLP ?

Do you mean “with(linalg):” by “with*linalg;” ?

According to

“The linalg package has been deprecated. Use the superseding packages, LinearAlgebra and VectorCalculus, instead.”
