X-Git-Url: http://gitweb.michael.orlitzky.com/?a=commitdiff_plain;h=417406c6a509462be431961a3dd1f13829b7cd96;hp=417406c6a509462be431961a3dd1f13829b7cd96;p=sage.d.git eja: replace rank computation with length of charpoly coefficients. If we cache the solution to the charpoly system instead, then the result is useful in more than one place (for the charpoly itself, in particular). ---
