Undefined symbol: 'delcols' [gctests.src

Excuse me, what is the reason for this error?

1 Answer


Literally, GAUSS is telling you that your code is trying to use delcols, but your GAUSS installation does not know what delcols is.

delcols is a GAUSS procedure that removes specified columns from a matrix. This procedure was added to GAUSS in version 18 or 19, I believe.

Most likely this error is occurring because you are using an older version of GAUSS to run code which requires a newer version.
