Arguments
| Type | Intent | Optional | Attributes | Name | ||
|---|---|---|---|---|---|---|
| integer(kind=ik), | intent(in) | :: | m |
Moment degree |
||
| real(kind=rk), | intent(in), | dimension(:) | :: | f |
Distribution function to take the moment of |
|
| real(kind=rk), | intent(in), | dimension(:) | :: | vPoints |
Coordinates of cell centres in velocity space |
|
| real(kind=rk), | intent(in), | dimension(:) | :: | vWidths |
Widths of velocity space cells |
|
| real(kind=rk), | intent(in), | optional, | dimension(:) | :: | g |
Optional velocity space array to include in moment integral |
Return Value real(kind=rk)
Description
Returns the m-th moment of passed distribution function harmonic - 4piint(v^(2+m)fdv). Optionally takes moment of f*g where g conforms to f. The integration is a simple Riemann sum.
