Problem with symbolic definite integral

Good afternoon,

I am trying to do a integration of a symbolic expresion:

syms s
p = (1/((2*pi)^(1/2)))*exp(-((s^2)/2));

% Parabolic cylinder function
f = @(D,m,ps)int(((s-D)^m)*ps,s,D,10);

f(2,3/2,p)

... But I obtain the following message:

Warning: Explicit integral could not be
found.

Any idea?

Thanks
