So the transfer function for the first equation g 1s say satisfies g 1s xs fs 1 s1 whilst the transfer function for the second equation g 2s satisfies g 2s ys xs 1 3s1 in pictorial terms this is shown in figure 28. If the first argument contains a symbolic function then the second argument must be a scalar.

In addition matlab will be used to perform the partial fraction expansion and to find the inverse laplace transform. This function is therefore an exponentially restricted real function. And where ut is the unit step function or expressed another way. From partial fraction expression we can easily write the inverse laplace transform as.
