Hi!
I have an analytic function f=sqrt(1+s)
And i want to turn it to the transfer function by the next code:
s=tf('s')
sys=sqrt(1+s)

But Matlab says:
Undefined function or method 'sqrt' for input arguments of type 'tf'
Could somebody help me with this issue? What should I do to overcome it?
Thanks!
