Bessel Kelvin Functions
bei(m, x)—Returns the value of the imaginary Bessel Kelvin function of order m.
ber(m, x)—Returns the value of the real Bessel Kelvin function of order m.
These functions, which have no scaled versions, can be evaluated both numerically and symbolically.
Arguments
m is a non-negative integer or vector.
x is a dimensionless real scalar or vector.
If both m and x are vectors, then they must be of equal lengths.
Additional Information
The mathematical relationship between the bei and ber functions and the Jn function is described in these symbolic evaluations:
