List of matrices bug Algebra

Inverting list LE is also different in CAS in AlgebraView

CAS: LE^-1 is correct and AlgebraView LE^-1=undefined

perhaps important LE is defined in CAS

invert(matrix) is the right form, not invert(list) you can do l1 = Zip(Invert(2Identity(3) - m), m, LE)

Zip((2Identity(3) - m)⁻¹, m, LE) works also

We have different handling of LE^-1 in CAS (inverting members of LE) and LE^-1 in AlgebraView (undefined). I also tried Zip, but was not successful in CAS but OK in ALgebraView - shouldn't we have consistent handling?

invert(M) = 2 Identity(n)-M

I do not need both (Elementarmatrices) - even your postet form do not work (5.0.518)...

BTW:

Product(LE) do not work in CAS - do you see an alternative way (not AlgebraView - is OK there)

there is ever two ways for operations on list: as list or as matrix

this seems change in CAS or algebra view

you can try Product(LE(n),n,1,Length(LE)) in CAS

or Product(element(LE,n),n,1,Length(LE)) if there is problem with short notation

I think there is a bug with the deep of zip of lists in CAS

Thank you, great,

I have not seen, not expected, to use Product in this way - it works, I cannot use short index notation (AlgebraView) because I want to have variables in matrices
