Convert OPC UA data object array to logical matrix

collapse all in page

Syntax

vLogical = logical(dObj)

Description

vLogical = logical(dObj) converts the OPC UA data object array dObj into a matrix of data type logical.

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

example

Examples

collapse all

Load the OPC UA example data file, convert the uaDataVis object to have the same time stamps, and create a matrix of type logical from the result.

load opcSampleUaData;
dUnion = tsunion(uaDataVis);
vLogical = logical(dUnion);

Input Arguments

collapse all

OPC UA data, specified as an OPC UA data object array. For more information, see Data.

Output Arguments

collapse all

OPC UA data values, returned as a matrix of logical type. vlogical is constructed as an M-by-N matrix of logical values, where M is the number of data values in dObj and N is the number of nodes in the array.
