         Application of Talbot's method to solve the PDE equation

			u_t (x,t) = u_xx (x,t),         x > 0,  t>0

	with conditions:
			u(x,0+)  = x*(x-1)
			u(0,t)   = 2*t
			u_x(0,t) = -1

	The analytical solution is

		u(x,t) = 2*t + x*(x-1)

	and its Laplace Transform is

		          2    x*(x-1)
		U(x,s) = --- + -------
		         s^2      s

	with a double pole at 0

	     and abscissa of convergence: sigma0 = 0
