These low latency exchange links have very high reliability with auto-failover and auto-recovery from hardware, software and network failures.
A user interface for networking GAUSS' multi-workspace, multi-threaded Engine. Parallel allows you to run multiple GAUSS programs, on local or remote computers, at the same time (i.e. parallel or concurrent programming) and then combine the results. It saves your work as you go and provides extensive undo functions.
SimGauss is a Non-Linear Simulation module for GAUSS. Requires GAUSSi to run.
It simulates non-linear differential equations and state-space systems with the choice of 8 integration algorithms, including variable order / variable step size. It also provides linearize and trim functions as well as parameter vectors and optimization (using optional GAUSS modules OPTMUM and MAXLIK)
Further information on SimGauss with a worked example. For sales information visit the Aptech Systems Inc. web site oremail (with anti-spam) them.
DataWiz is DOS based statistical spreadsheet for large GAUSS datasets.
DataWiz allows interactive spreadsheet viewing, editing and transformations. It works with GAUSS numeric and character datasets with upto 8175 columns and up to 2G bytes of data (Small Data Set v89 format). It allows interactive correction of transformation errors and data set validation.
FastSort is a very fast sorting module for GAUSS. Requires GAUSS to run.
FastSort provides faster and more flexible sorting functions than Gauss' standard matrix and dataset sorting routines. Unlike most sorting routine, the time FastSort takes to sort is essentially linear with the number of elements to be sorted ( i.e O(n) ). Almost all other sorting routines take more than proprotionally more time to sort more elements ( ie. O(n log n)).
FastSort will sort datasets as large as your hard disk will hold, unlike Gauss' sortd command which is limited to datasets that will fit entirely in memory. FastSort also lets you specify a scrap dataset to capture any data not sent to the output dataset when using a unique sort. You can also define you own character sort order
QueGauss is a discrete simulation module for GAUSS. Requires GAUSS to run.
QueGauss allows you to simulate discrete systems involving queues. These include such things as hospital patient services, manufacturing processes and phone exchanges. Using QueGauss you can examine the statistics of waiting times, transit times and utilization of resources.
CtrlGauss is a control system transformation and analysis module for GAUSS. Requires GAUSS to run.
CtrlGauss provides the tools to analyze and design control systems. "Classical" transfer function and "modern" state-space representations, both continuous and discrete are supported. Functions are provided to all frequency domain design, both continuous and discrete, using Nichols, Nyquist, Bode and Root Locus methods. Building systems and simulation functions are also provided so you can build your closed loop system and simulate its response.
Time:Frame is a revolutionary web based interface which allows non-technical users to construct complex timebased queries. These queries answer who did what, when and for how long. These queries are then answered by TimeCube.
Time:Frame is a Java based front end application which talks via a servlet server to the TimeCube back end. All the user's data is saved on the serve so the user can log in from a different machine and continue from where they left off.
The MFD Toolbox provides M-file design tools for multivariable system analysis and control design. Requires MATLAB 4 to run.
It covers multi-input/multi-output (MIMO) systems, where the basic element is the multivariable frequency response (MVFR) matrix. Support is also given for state-space and transfer function matrix forms, both in continuous and discrete time. Functions exist for assessing column- and row-dominance, Gershgorin and Ostrowski bands, relative gain arrays and design tools for control, such as Nyquist Array Methods, Edmunds' Algorithm, and the Quasi-Classical Method. Visualization utilities exist for plotting and annotating system frequency responses. This Toolbox was developed for GEC (UK).
