ilaplace(GP,s,t)
the output came (its very long to post here just run the programm once and see the output and in that output it is in terms of s again what to make of that
any explaination

If ilaplace can't find a closed form expression it returns the result in terms of "root," which can then be evaluated numerically if needed. For example:
>> vpa(ilaplace(GP),5)
ans =
[ 0.0017395*exp(-0.03183*t) + 5.9665e-7*exp(-9.1133*t) + 0.0039189*exp(-0.21191*t), 0.0018424*exp(-0.03183*t) + 0.000037273*exp(-9.1133*t) - 0.0018797*exp(-0.21191*t)]
[ 0.0018424*exp(-0.03183*t) + 0.000037273*exp(-9.1133*t) - 0.0018797*exp(-0.21191*t), 0.0019524*exp(-0.03183*t) + 0.0028045*exp(-9.1133*t) + 0.00090214*exp(-0.21191*t)]
[ 0.0018496*exp(-0.03183*t) - 0.000037605*exp(-9.1133*t) - 0.001812*exp(-0.21191*t), 0.0019598*exp(-0.03183*t) - 0.0028296*exp(-9.1133*t) + 0.00086974*exp(-0.21191*t)]
