When you run csound -z1, do you find the la_* opcodes in the list?
If not, your installation or build of Csound lacks these opcodes. To
build them, you need the Gmm++ library (header files only) referenced
in the Csound manual.
If so, I wish I had good examples to offer. Have you read the section
on the opcodes in the manual? This needs to be read very carefully,
because the linear algebra opcodes do not represent objects the way
the other opcodes do; essentially a pointer to an array is stuffed
into an irate variable and used at krate or arate. This is necessary
to enable signals to be read from audio streams into arrays, and back
out again, when the size of the array and the size of ksmps are not
necessarily the same. This is similar to fsigs, actually.
If you will tell me what you would like to do, and if I can understand
what it is you would like to do, I would love to work with you to
develop a working example for the manual.
Hope this helps,
Mike
