it's k sir.F(s,u)=
how to calculate the inverse transform of this transformation sir

That looks like it is closely related to a Laplace transform -- it would be the Laplace transform for the case of u = 1.
Under the assumption that s and u are both > 0 then you can probably relate it to the Laplace transform.

Yes sir it is closely related to laplace transform we have relation between these 2 transformations i.e
where 
is laplace transform.But i don't know how to write code for this transformation in matlab. If anyone knows please help me.

Use the symbolic toolbox and laplace() or ilaplace()

F = @(s,u) laplace(s/u);
I do not believe that there is a unique inverse for F(s,u) unless u is given explicitly

and 
and 
S is shehu transformation. i solved it manually using the formula of F(s,u) it is giving same results but i don't know how to calculate these things in manually.
