The function
where 
is a complex number and 
is a real number. It satisfies the inhomogeneous Bessel equation
For non-integral 
the following expansion is valid:
If 
and 
, the following asymptotic expansion is valid:
where 
is the Neumann function. If 
is not an integer, the Weber function is related to the Anger function 
by the following equations:
The Weber functions were first studied by H. Weber [1].
