arrayHasSameTimeStamp
Class: opc.hda.Data
Namespace: opc.hda
True if all elements of OPC HDA data object have same time stamp vector
Syntax
tf = arrayHasSameTimeStamp(dObj)
Description
tf = arrayHasSameTimeStamp(dObj)
returns true if all the
elements of dObj
have the same time stamp.
Use tsunion
to ensure that the time stamps
of an OPC HDA data object are the same.
Examples
Load the OPC HDA example data file and see if the
hdaDataSmall
object has the same time stamps in all
elements:
load opcSampleHdaData; tf = arrayHasSameTimeStamp(hdaDataSmall);
Form a new data set using tsunion
, and check the time
stamps again:
hdaUnion = tsunion(hdaDataSmall); tfU = arrayHasSameTimeStamp(hdaUnion)
