Modeling, design, and analysis of continuous-time or discrete-time linear time invariant (LTI) control systems. Ch Control System Toolkit can be conveniently used for modeling, design, and analysis of continuous-time or discrete-time linear time invariant (LTI) control systems. A control system can be modeled in the form of transfer functions as shown in a block diagram below, zero-pole-gain, or state-space. Ch Control System Toolkit supports most classical and modern control techniques through object-oriented programming based on a control class. It can seamlessly interface existing C/C++ code in either source code or binary static/dynamical libraries without re-compilation. It can even be embedded in other application programs. The software comes with sample code for each member function of the control class.

Design and analyse mechanisms. Ch Mechanism Toolkit can be used for design and analysis of many different mechanisms such as fourbar linkage, crank-slider mechanism, sixbar linkages, cam-follower system, etc. Ch Mechanism Toolkit is developed in Ch Professional Edition with user friendly high-level numerical and graphical plotting capabilities, as well as easy-to-use QuickAnimation for quick animation.

Cross-platform C/C++ Interpreter. Ch is an embeddable C/C++ Interpreter for cross-platform scripting, 2D/3D plotting, numerical computing, shell programming, quick animation, and embedded scripting. Ch Professional Edition is a C/C++ compatible interactive platform for scientific computing and scripting. Ch Professional is especially effective for teaching and learning including Introduction to Computing, Algorithms, Computer-Aided Problem Solving, and Computer Programming. Ch can execute C/C++ code directly without compilation and without intermediate code.

Two- and Three-dimensional graphical plotting for C/C++. SoftIntegration Graphical Library (SIGL) is a cross-platform C++ graphical library. It provides one of the simplest possible solutions for two- (2D) and three-dimensional (3D) graphical plotting within the framework of C/C++ for rapid application development and deployment. SIGL is for applications where the convenience of use, speed, performance, and cost matter. SIGL can save you from significant development and maintenance cost. With SIGL, you can design and deploy your engineering and science applications with visualization across different platforms.

Generate enterprise web applications and executive dashboards from your Excel spreadsheets, including active charting, high-speed calculations, and rich interfaces. KDCalc converts your Excel spreadsheets into client or server applications that run without Excel. KDCalc compiles your Excel cell formulas and data into high-speed calculation engines, and also generates ASP.NET, ASP Classic, JSP, and HTML user interface applications that have the same look and interactivity as your formatted spreadsheets, now including forms controls and live charting! The most common use of KDCalc is to execute Excel spreadsheet models as server applications, free from the scalability and throughput limitations of Excel. KDCalc has built-in features that facilitate failover, load balancing, and XML-based recalculation. Designing, Building, and Testing your complex business applications and dashboards with Excel and KDCalc can be as much as 50 times faster than hand-coding in Java, C#, or VB.NET.
