How can I multiply each element of a polynomial with different coefficients??

Lts say I have a function in s domain, using iLaplace code at end I have an inverse laplace at the form of: exp(t)+exp(-2t)+t+5 How can I make this polynomial to be like c1*exp(t)+c2*exp(-2t)+c3*t+5*c4*??

exp(t)+exp(-2t)+t+5 is not a polynomial!

What does: I have exp(t)+exp(-2t)+t+5 actually mean in matlab code? What do you actually have?

[sara hosseini]

this is my function in "s" domain:

(-0.00000704*(s*f3+f3_p)+0.000011*(s.^3*f3+s.^2*f3_p+s*f3_pp+f3_ppp))./(-s.^2*0.00000704+s.^4*0.000011)

taking ilaplace of this function gives:

-0.03*exp(0.8*t)+0.03*exp(-0.8*t)+1.57*t+5

now I want to multiply each element of this function with a coefficinet c1,c2,c3,c4 that I have :

-0.03*exp(0.8*t)*c1+0.03*exp(-0.8*t)*c2+1.57*t*c3+5*c4

c1*exp(t)+c2*exp(-2*t)+c3*t+5*c4

if your c1 to cn are also arrays with the same dimension as t-series

    c1.*exp(t)+c2.*exp(-2*t)+c3.*t+5*c4
