Is this a memory leak, since y is dynamically allocated but it's given

Yes, it is a leak. You don't need to create the RowVector object with
new. The memory for RowVector, octave_value, and nearly all other
objects in Octave is managed by reference counting.
Right, just as I thought.
I tried running octave through valgrind, but I don't get any output..
What options did you use for valgrind?
$ valgrind --leak-check=full octave --eval "pkg load
gsl;A=legendre_sphPlm_array(10,10,0.0);"

==6971== Command: octave --eval pkg\ load\
gsl;A=legendre_sphPlm_array(10,10,0.0);

octave: X11 DISPLAY environment variable not set
octave: disabling GUI features
Without the semicolon you see the array, but again the usual valgrind
output is missing..?
