Calculates the Bessel function of the second kind of the order 0.
Syntax
Y0(Number)
The syntax of the Y0 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.
The real Bessel function is calculated for a real argument. A void floating point value is output for values smaller than or equal to zero. The result then has the 64-bit floating point value data type. The following illustration shows the course of the function within the interval [0.01, 50]:
If Number is complex, the complex Bessel function is calculated. The result then has the complex 64-bit floating point value data type. The following illustration shows the course of the absolute value of the function:
If the argument is a list, then the function is executed for each element of the list and the result is also a list.
