Bridging the gap between acquisition and analysis by providing direct access to live, measured data from MATLAB, the Data Acquisition Toolbox provides a natural extension to MATLAB and offers engineers a single, integrated environment to support their entire analysis and development processes. The toolbox provides a full set of functions for controlling and communicating with a variety of off-the-shelf, PC-compatible hardware. The open and extensible environment allows users to easily customize their acquisitions, access the built-in features of external hardware devices, and incorporate the powerful analysis and visualization features of MATLAB and its companion toolboxes into their design. Version 1.0 supports sound card devices as well as acquisition hardware from National Instruments and Hewlett Packard. The toolbox is compatible with Windows 95/98/NT and requires MATLAB 5.3.
