Hewlett-Packard MATLAB Interface to VXI Hardware
Hewlett-Packard's MATLAB Interface to VXI hardware enables a customer familiar with MATLAB to set up and control the HP E1432A, HP E1433A, and HP E1434A VXI multichannel measurement hardware. This interface, developed using HP's standard VXI Plug & Play Library, supports simultaneous sampling rates up to 196,608 samples/sec/channel for hundreds of channels. The interface can transfer binary data online to arrays in the MATLAB workspace at rates up to 4 Mb/sec with an external 300 MHz Pentium II PC. MATLAB provides the flexible data analysis tools that are typically needed in online measurement and analysis systems dealing with sound, vibration, and general-purpose data acquisition.
The HP E1432A and E1433A digitizers provide data in four domains: time, frequency, and (for rotating machine measurements) angle and order. These versatile digitizers also provide an optional single-channel arbitrary source or an optional dual-channel tachometer. The HP E1433A provides optional real-time octave or third octave spectra.

The E1432A is a 16 channel VXI module providing simultaneous, alias-free sampling at rates up to 51,200 samples/sec on all channels. The HP E1433A is an 8 channel VXI module providing simultaneous, alias-free sampling at rates up to 196,608 samples/sec on all channels. The HP E1434A is a 4 channel arbitrary source with built-in sine and random waveforms with 16- or 20- bit resolution.

Simulink Interface to GT-Power Engine Simulation Software
Gamma Technologies now offers CPower, a product developed jointly with Arthur D. Little that links GT-Power, a leading engine simulation program, with MATLAB and Simulink to provide a flexible environment for analyzing engine control strategies. In this environment, the user places sensors and actuators in the GT-Power model that pass GT-Power state variables (such as pressure, temperature, mass flow, and engine speed) to Simulink at every time step of the simulation. Simulink then uses these as inputs to control elements and calculates new GT-Power input variables. These new input variables (throttle position, fuel rate, injection timing, spark timing, and so on) are passed back to GT-Power, via actuators, to meet some desired target. Users can now develop, test, and refine their engine simulations and their control strategies within one integrated environment.
