Description Usage Arguments Details Value Author(s) Examples
Calculate the residue of a complex-valued function using limits. Note that this function only works for simple poles.
1 | residue(f, z0)
|
f |
A function whose residue to be calculated. |
z0 |
A real or complex number at which the residue is evaluated. |
This function calculates Res(f,z_0) by taking the limit of (z-z_0)f(z) as z -> z_0. Therefore, z0 should be a simple pole (including one on the branch cut; see Examples).
The calculated residue.
