NIMEX is a C-language interface to National Instruments NIDAQmx data acquisition drivers that are exposed for use as objects in MATLAB (@nimex/@daqjob). This provides an alternative to the objects provided by the Matlab Data Acquisition toolbox, which have several functional limitations.
The preferred method of acquiring Nimex (in binary form) is as a part of Ephus, but it can also be downloaded independently below.
The runtime requires NIDAQmx 8.5(.0f5 or better) and the GTK Runtime (website or local copy).
