Syntax

Vint16 = int16(DObj)

Description

Vint16 = int16(DObj) converts the OPC HDA data object array DObj into an int16 matrix.

DObj must have the same time stamps for each of the Item IDs (elements of DObj), otherwise an error is generated. Use tsunion, tsintersect, or resample to generate an OPC HDA data object containing the same time stamp for all items in the object.

Examples

collapse all

Load the OPC HDA example data file, convert the hdaDataSmall object to have the same time stamps, and create an int16 matrix from the result.

load opcSampleHdaData;
dUnion = tsunion(hdaDataSmall);
Vint16 = int16(dUnion);

Input Arguments

collapse all

OPC HDA data, specified as an OPC HDA data object array.

Output Arguments

collapse all

OPC HDA data values, returned as an int16 matrix. Vint16 is constructed as an M-by-N matrix of int16 values, where M is the number of items in DObj and N is the number of time stamps in the array.
