Hello,

I wanted to use lapack to calculate eigenvalues of a (square) matrix,
but I see an error:
(Important is just the second part, hh is a square matrix.)

h=.(-i.6) |."0 _ (0 1 0 0 0 1)
hh=.<.?(10*h)
hh=.hh + (|: hh)

load 'math/lapack'
load 'math/lapack/geev'
geev_jlapack_ hh
|domain error: cd
| r=.x cd LASTIN=:y

Can anybody tell me what this error means?

Thank you!
Ruda
