DIFF differentiates the data in AO. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% DESCRIPTION: DIFF differentiates the data in AO. The result is a data series the same length as the input series. In case of method 'diff' computes the difference between two samples, in which case the resulting time object has the length of the input series -1 sample. CALL: bs = diff(a1,a2,a3,...,pl) bs = diff(as,pl) bs = as.diff(pl) INPUTS: aN - input analysis objects as - input analysis objects array pl - input parameter list OUTPUTS: bs - array of analysis objects, one for each input, containing the differentiated data Parameters Description REFERENCES: [1] L.

METHOD | '3POINT' |
|
The method to use. Choose between:
|
F0 | '1/Nsecs' | none | The pole frequency for the 'filter' method. |
ORDER | 'FIRST' |
|
Derivative order. This applys only to the cases where 'METHOD' is set to:
|
COEFF | [] | none | Coefficient used for the derivation. This applys only to the case where 'METHOD' is set to 'FPS'. Refer to the fpsder help for further details |
