Hi everyone,
The following code calculates the elements of matrises (x6). But in the result there are some characters like #1,& vs.
And I couldn't success to express the result without these characters. Is there anyway to express more clear result? Please help!!!!!!!!!
Thanks in advance
A = {{0, -R, 0, 0, 0, 0}, {(-Gamma^2*R^3*k)/Dnn, 0, -1,(R*(1 + Gamma^2))/Dnn, 0, 0}, {0, 1, 0, 0, (R*(1+ Gamma^2))/Dtt, (-R^2*Gamma^2)/Dtt}, {0, 0, 0, 0, -1, R}, {0, 0, 0, 1, 0, 0}, {k*R, 0, 0, 0, 0, 0}}
expmat = MatrixExp[t*A]
expmat // MatrixForm
FullSimplify[expmat[[1, 1]]]
