Hi,
I am playing with MatrixExp in Mathematica 7.
Input:
"mmaatt[a_, b_, c_] := {{a, 1, 0}, {1, b, 2}, {2, 3, c}}
a = 1;
b = 2;
c = 3;
Log[Tr[MatrixExp[mmaatt[a, b, c]]]]"
However, I got very weird output with # and & symbols as follows. Could someone explain it to me ? Thanks!
"Log[RootSum[-1 + 4 #1 - 6 #1^2 + #1^3 &, (-5 E^#1 #1 + E^#1 #1^2)/(
4 - 12 #1 + 3 #1^2) &] +
RootSum[-1 + 4 #1 - 6 #1^2 + #1^3 &, (
3 E^#1 - 4 E^#1 #1 + E^#1 #1^2)/(4 - 12 #1 + 3 #1^2) &] +
RootSum[-1 + 4 #1 - 6 #1^2 + #1^3 &, (
E^#1 - 3 E^#1 #1 + E^#1 #1^2)/(4 - 12 #1 + 3 #1^2) &]]"
