No, the la opcodes are not in the csound -z1 list.
I'm on OSX. Must I install the Gmm++ library before running the
installer for being able to use the la opcodes? Or is the installer
incomplete? (By the way, I don't see the opcodes one for one in the
manual - just the Linear Algebra Opcodes page in general.)
I have no particular goal with the la opcodes at the moment. I wanted
to learn about their abilities, and I thought they could perhaps offer
another way of working with arrays instead of the often somehow
complcated way working with function tables. In each case, some simple
examples would be a good idea, in my opinion.
