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].
