Inverse Laplace working in command window but not in editor

Hi there, I am writing a script to solve laplace and inverse laplace functions.  When I call the inverse laplace function in the command window, it works fine.  However, when I call it in the script itself, it does not seem to work.  Anyone have any ideas? Below is my code.

Script code:

%---- Inverse Laplace Solver ----%

%------------DOESN'T WORK--------%

clear all

prompt = "What do you not want to do?:";

f = input(prompt);

syms s t

ilaplace(f)

Command window code:

>> ilaplace(1/(s-4))

ans =

exp(4*t)

Change the script code to

clear all
syms s t
prompt = "What do you not want to do?:";
f = input(prompt);
ilaplace(f)

f is an input to the “ilaplace” function and this input should be specified as a symbolic expression, symbolic function, symbolic vector or symbolic matrix.

clear all at the beginning will clear the entire workspace and before you take the input f from the user the independent variable s and Transformation variable t should be defined.

Hope this helps!
