Expected output?

Things have changed from Maple 15 to Maple 16, but anyway: could you please post the output you expect? Thanks.

Fixed

I missed a line in your post, "LinearAlgebra[Transpose](map(Dagger, P))". Dagger was using LinearAlgebra:-HermitianTranspose, but you are right, the matrix components may be operators, and in these cases, as the one you posted, LinearAlgebra:-HermitianTranspose will not work as expected.

It's fixed now in the Maple version under development.

yes - operators inside a matrix

yes, exactly - in my work I often have a case where a I deal with a tensor product of (say) two hilbert spaces - one very small, the other large or infinite. So it would be nice to be able to represent the small one using the matrix formalism (i.e. with LinearAlgebra) and keep the operators on the other in the operator-form, and yet have the simplifications/etc work correctly.

Do you have an idea when we can expect an update to be publically released?

thanks

it works fine in Maple 16.02

Hi,

Just revising this old post - the fix got into the system and examples as the one you posted work fine in Maple 16.02.
