All data returned from OPC HDA servers can be stored in MATLAB^® as an OPC HDA data object.

OPC HDA data read operations can produce a large amount of data returned to MATLAB.

OPC HDA data objects provide initial data storage, visualization, and manipulation functions for you to work with OPC historical data in MATLAB.

Retrieve very large data sets from OPC historical data access servers.
