I'm trying to plot the inverse Laplace transform of Code ( (Unknown Language)): >>syms s >>Ys3 = (80000*s^2 + 400000*s)/(s^5 + 30*s^4 + 395300*s^3 + 11850000*s^2 + 202500000*s); So I take this function and calculate its inverse laplace transform and I get this, Code ( (Unknown Language)): >>yt3 = ilaplace(Ys3); >>yt3 = sum((400000*exp(r3*t) + 80000*r3*exp(r3*t))/(4*r3^3 + 90*r3^2 + 790600*r3 + 11850000), r3 in RootOf(s3^4 + 30*s3^3 + 395300*s3^2 + 11850000*s3 + 202500000, s3)) Needless to say, I'm stumped as to how I can graph this using the plot function. Because I don't know how to express the above result into something I can plot. Thus my dilemma. Anyone knows how to get around this? Thanks.
