Harshit Baghel's "Answer" moved here and formatted correctly:

I am using fi function to change the data type of the array it is showing the error shown below

Trial>> d = fi(s,1,10,23)
Error using embedded.fi/fifactory
Unable to check out a license for the Fixed-Point Designer.

Error in fi (line 222)
a = embedded.fi(varargin{:});

I am using 30 days trial version currently.

I don't see what's unclear about the error message. You do not have a license for the Fixed-Point toolbox (or it's not installed properly).

If you're supposed to have such license, then contact Mathworks or whomever is responsible for managing your license.
