I tried appending the linearalgebra tests to share_testsuite. Something has
changed with 'expand' since I last ran test-matrixexp, I think. An example:
(%i37)
(%e^(-2*sqrt(2))*(%e^(2*sqrt(2))+2*%e^sqrt(2)+1)^2)/16+(%e^(-2*sqrt(2))*(%e^(2*sqrt(2))
-2*%e^sqrt(2)+1)^2)/16-(%e^(-2*sqrt(2))*(%e^(2*sqrt(2))-1)^2)/8$
(%i38) expand(%);
(%o38) %e^(2^(3/2)-2*sqrt(2))/2+1/2
(%i39) expand(%,0,0);
(%o39) 1
Ideas?
