Matrix input in CAS Classic 6

Not a Problem

When I type an expression as {{2, 1, 3}, {1, -2, 4}} in the Algebra it is recognized and displayed as a matrix. However in Classic 6.0.546 CAS doesn't recognizes it as a Matrix and Matrix commands return question marks. When clicking in the CAS row it does show a matrix but beneath the weird result remains and commands still don' work.

it is recognized when working with := an also if I just type the list definition {{1,2},{3,4}}, but not if I type A =

OK I should work with A:= ... but I still find the result strange

Isn't this ok? (morning Chris)I think that the assignment := is correct once you want to define an object.

= is used for equations

Or am I missing something?

indeed Simona, I realized

I see that anyway, if you change the definition of matrix A (adding a :=) in 1st CAS row, the following rows don't acknowledge the change.

Please try in the new CAS app beta.geogebra.org/cas (we are unlikely to make any changes now in the Classic CAS View)
