Sorry for delay with answer.
J supports double-precision complex numbers ('Z' in LAPACK), not single-
precision ('C'). So, you should look for zgee*.ijs scripts instead.
By the way, a lot of math/lapack2 wrappers are in math/mt addon's test suite.
In particular, xGEEV family wrappers are in test/lapack2/geev.ijs script:
mat=. j./ i. 2 3 3 NB. sample matrix
load 'math/mt'
load 'math/mt/test/lapack2/geev'
'w Vl Vr'=. 'vv' zgeev mat
NB. 'vv' here is to get both left and right eigenvectors
