Y1 (FPScript)
Calculates the Bessel function of the second kind of the order 1.
Syntax
Y1(Number)
The syntax of the Y1 function consists of the following parts:
Part |
Description |
|---|---|
Number |
The argument for the function. All data structures are allowed. All numeric data types are permitted. |
Remarks
The data type of the result is always 64-bit floating point.
The structure of the result corresponds to that of the argument Number. The calculation is done element-by-element where appropriate.
The result has the unit 1, if Number has a unit. Otherwise, it has no unit.
For aggregate data structures, only the Y component is calculated. A void floating point value is output for values smaller than or equal to zero.
The following illustration shows the course of the function within the interval [0.01, 5]:
If an argument is a list, then the first element in the list is taken. If this is also a list, then the process is repeated.
