|PARI-GP use of elldata & seadata packages|
As a PARI-GP newbie, I could use a little help in installing
or activating the optional “elldata” and “seadata” packages.
I installed PARI-GP 2.5.0 running under Windows 7 SP1 and User
Guide examples seem to work normally.
I then downloaded, unzipped and copied the extra packages to the
PARI-GP (gp.exe) executable folder [C:\Program Files (x86)\PARI\]
1. A folder named elldata containing 200 files named ell0 thru ell199
2. A single file named seadata (no filename extension) size 39,870KB
The User Guide elliptic functions seem to work e.g.
E = ellinit([0,0,0,-4,0]) outputs voluminous curve parameters
allap(E,11) correctly outputs = 0 but
*** ellidentify: Elliptic curves files not available for conductor 64
[Missing C:/Program Files (x64)PARI/elldata/ell0].
[Note missing “/” between (x64) and “PARI”]
*** unknown function or error in formal parameters: elsea(E,97).
I would appreciate any suggestions to access the elldata & seadata
