X-Git-Tag: v8.4.0-rc2~42^2
X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=85d681a9d2d7e5e87536e7ad092aaf1bef7b543d;p=dealii.git

avoid warning about unused variable

According to the documentation of ArpackSolver::solve the first parameter is
unused. Do not give it a name in the definition to avoid unused variable
warnings.
