bessel (MathScript RT Module Function)
Owning Class: advanced
Requires: MathScript RT Module
Syntax
jv = bessel(v, x)
jv = bessel(v, x, 1)
[jv, error] = bessel(v, x)
[jv, error] = bessel(v, x, 1)
Description
Computes the Bessel function of the first kind of a given order.
Inputs
| Name | Description |
|---|---|
| v | Specifies the order of the Bessel function. v is a real, double-precision, floating-point positive scalar, vector, or matrix. |
| x | Specifies the value for which you want to compute the Bessel function. x is a real or complex, double-precision, floating-point scalar, vector, or matrix. |
| 1 | Scales the computation. bessel_j(v, x, 1) scales bessel_j(v, x) by exp(-abs(imag(x))). |
Outputs
