CRYSISFPS.M- CRYTEK GAME ENGINE BENCHMARK ON 8800GTX SLI SYSTEM Graphics Hardware is often benchmarked by how it performs under load- like in intensive 3D games. A measure of the system performance in the game is how many Frames Per Second (FPS) it can render.

>> Y = cummean(X,DIM); if X is MxN, Y is also MxN. To illustrate the functionality, lets assume X is a 1xN vector. Then, Y is a 1xN vector where the n-th entry in Y is given by mean(X(1:n)). So, Y(end) = mean(X), and Y(1) = X(1). cumvar works in the same way, and this can be done on an arbitrary dimensional X along dimension DIM.

The AudioDevice blocks that ship with Signal Processing Blockset utilize the PortAudio library to communicate with the audio hardware. Although the PortAudio library supports a range of API's designed to communicate with the audio hardware on a given platform, the following choices were made for the version of PortAudio that is built for Simulink: Windows: DirectSound Linux: OSS Mac: CoreAudio If you wish to enable communication between Simulink and your audio device using a different API, it is possible to build your own version of the PortAudio library and use it in place of the PortAudio library that ships with the Signal Processing Blockset.

This basic model shows you how to acquire live data from a Tektronix oscilloscope into Simulink. This model was developed for the Tektronix TDS 2012 oscilloscope but may work with other Tektronix scopes with little or no modifications. To view the results, double click on each "scope" block in the model to view the waveform acquired, then right click and select "Autoscale".

This basic model shows you how to acquire live data from an Agilent oscilloscope into Simulink. This model was developed for the Agilent 6000 series oscilloscope but may work with other Agilent scopes with little or no modifications. I welcome submission reviews below to let us know whether you got it working with your specific Agilent scope.

These are two M-files 'fourier1' and 'fourier2' The first is designed to demonstrate how triangular, rectangular, saw tooth, half wave and full wave rectified signals can be built from superposition of a predefined no of Fourier harmonic terms. It demonstrates how increasing the number of terms included in the summation will improve the signal shape.
