FAMOS中有一个leng？函数不知道怎么用，有谁能给个详细的说明

Leng？是得到曲线的采集点的总数。详情见下说明：



Function

Returns the length (number of points) of a waveform.

Declaration

Leng?(XXWave) -> SvLeng

Parameter
Definition

XXWave
Waveform or single value whose number of points (length) should be
determined

-> SvLeng
Length of XXWave


Description

This function returns the length (number of points) of a waveform.

Remarks

A number of points is returned, not an x-coordinate difference.

The function Leng? is located in function group "16> Properties I"

Example

SvDurat = xDel?(NwData) * Leng?(NwData)

The duration of a waveform equals: Number of points * Sampling rate.

NwNormHi= 100'%' *Histo(NwData,0,0)/Leng?(NwData)

A histogram is normalized to 100% by dividing by the total number of
points in the waveform.

SvOne = Leng?(100)

The length of a single value is defined as one.

SvZero = Leng?(EMPTY)

An empty waveform has a length of zero.
