<p>

These functions return the first derivative with respect to <span class="emphasis"><em>x</em></span>
|
||
of the corresponding Bessel function.
|
||
</p>
|
||
<p>
|
||
The return type of these functions is computed using the <a class="link" href="../result_type.html" title="Calculation of the Type of the Result"><span class="emphasis"><em>result
|
||
type calculation rules</em></span></a> when T1 and T2 are different types.
|
||
The functions are also optimised for the relatively common case that T1 is
|
||
an integer.
|
||
</p>
|
||
<p>
|
||
The final <a class="link" href="../../policy.html" title="Chapter 21. Policies: Controlling Precision, Error Handling etc">Policy</a> argument is optional and can
|
||
be used to control the behaviour of the function: how it handles errors,
|
||
what level of precision to use etc. Refer to the <a class="link" href="../../policy.html" title="Chapter 21. Policies: Controlling Precision, Error Handling etc">policy
|
||
documentation for more details</a>.
|
||
</p>
|
||
<p>
|
||
The functions return the result of <a class="link" href="../error_handling.html#math_toolkit.error_handling.domain_error">domain_error</a>
|
||
whenever the result is undefined or complex.

There are two sets of test values: spot values calculated using <a href="http://www.wolframalpha.com/" target="_top">wolframalpha.com</a>,
|

and a much larger set of tests computed using a relation to the underlying
|

Bessel functions that the implementation does not use.
