Dear J Jusers, Earlier I used *LAPACK* in the *J602a* and *J804* versions without any problems.
I installed the *J903* version along with *LAPACK* based on *System/Installation/J903/AIO*. I repeated the installation several times, but it does not run, it *always gives an error*. I tried running the *Addons/math/lapack* example, but I kept getting an error message. After load 'math/lapack math/lapack/dgeev' not found: c:/users/tulajdonos/j903/addons/math/lapack/lapack.ijs |file name error: script | 0!:0 y[4!:55<'y' I getting error message. It was the same problem after load 'math/lapack2 math/lapack2/dgeev' not found: c:/users/tulajdonos/j903/addons/math/lapack2/dgeev.ijs |file name error: script | 0!:0 y[4!:55<'y' Has anyone had a similar experience? How to install LAPACK on J903? Thank you in advance for your kind help.
