Arguments

Type IntentOptional Attributes Name
real(kind=r8), intent(inout) :: data(:)

Sequence to be filtered.
integer, intent(in) :: ord

Order (#poles), not to exceed 10.
real(kind=r8), intent(in) :: cutoff

High-frequency cutoff of filter [Hz].
real(kind=r8), intent(in) :: ts

Sampling interval [sec].
logical, intent(in) :: passes

Forward filtering only if true, else forward and reverse (zero phase).
