Dear Ravi,

You can use the command : ilaplace(F,trans_var,eval_point)

F is Symbolic expression or function, vector or matrix.

This is an example: 

syms x y

F = 1/y^2;

ilaplace(F, y, x)

ans= x

**************************

syms a s x

F = 1/(s - a)^2;

ilaplace(F, x)

ans= x*exp(a*x)

Try the Laplace program samples about ilaplace function given on the help at :

http://www.mathworks.com/help/symbolic/ilaplace.html.

You can use the ilaplace function.

Thank you all you for your valuable answers and suggestions. But I want to find the Laplace transform with the help of MuPAD note book. 

Thank you
