Hello,
This could be an easy question for many but for the life of me i could not solve it
I have a
syms x y
laplace(sqrt(x))
ans =
pi^(1/2)/(2*s^(3/2))
Now I want to convert laplace domain Numerator and denominator to TF(num,den) so that i can use it further.
How to achieve this?

Hi,
For that you can simply use ilaplace function as ilaplace corresponds to inverse laplace which is used for converting s domain to t domian (time) and hence you'll obtain numerator and denominator form transfer function.
Here is the documentation link:

Hope this helps!

Try using tf function and then choose specific command type accordingly in the manner you want your transfer function to look like.

Hi Aman,
I tried that, tf function from Matlab does not handle fractional powers
