O-Matrix

by Harmonic Software

O-Matrix is an integrated environment for analyzing and visualizing data, and building turnkey scientific and engineering computing solutions. The program includes hundreds of engineering and statistical functions for solving a broad range of technical computing problems. Easy-to-use and flexible plotting commands enable you to rapidly build design prototypes, and implement sophisticated systems.

The foundation of O-Matrix is a high-performance matrix language that is specifically designed for high-performance technical computing. The notation of this language will dramatically reduce your design and implementation efforts, and enable the construction of systems that execute far quicker than other interpreted environments. O-Matrix also provides a compatibility mode that enables you to run MATLAB© m-files. This enables you to leverage existing m-files, and simplifies the transition to O-Matrix for users experienced with MATLAB.

The O-Matrix environment is interpreted which means your commands are immediately executed as you enter them. Textual output is displayed in the Command window, and plotting commands are displayed in one or more Graphic windows. The environment provides a debugger for debugging, analyzing, and profiling complex algorithms.

Plotting in O-Matrix is easy-to-use and flexible for creating presentation plots.

O-Matrix excels as both a prototyping environment, and a tool for implementing sophisticated systems. You can use O-Matrix, to perform what if types of analysis by entering single line commands or scripts and viewing the results, or you can build extensive, GUI-based systems.

O-Matrix Performance

O-Matrix has been designed from the ground up for accuracy and high-performance. The O-Matrix environment enables you to both prototype designs and perform large scale analysis within the integrated environment. O-Matrix has been built using highly optimized C/C++, FORTRAN, and assembly code to provide optimal execution performance. The linear algebra routines in O-Matrix are based on the algorithms from BLAS, LINPACK, and LAPACK to provide robust, accurate solutions.

O-Matrix Analysis Functions

O-Matrix provides an extensive set of functions for implementing solutions in a broad range of technical computing disciplines. Functions are highly optimized and designed to be easy-to-use for prototyping applications and extensible for specialized requirements. Most functions include complete source code to allow you to review the implementation and modify it to your own requirements if necessary. The following function types are available:

• Linear Algebra
• Statistics, Special Functions and Simulation
• Curve Fitting, Optimization and Derivatives
• Fourier Analysis and Filtering
• Integration and Differential Equations
• Polynomials
• Elementary Functions

O-Matrix Plotting and Data Visualization

O-Matrix provides a broad range of functions and tools for plotting and visualizing technical data. O-Matrix makes it easy to formulate, test, and explore alternative ideas. Typical plots can be created by entering a single statement at the O-Matrix command prompt or sophisticated, highly-customized plots can be generated by creating script files. Plotting script files enable the easy regeneration of plots for multiple data sets, iterations of a model, or repeated experiments.

Plot attributes and characteristics such as line thickness, tick mark spacing and style, layout, font properties, and labels can be customized to create specialized plots. Plots can be exported as either bitmap or vector-based images for import into other applications such as Microsoft Word, PowerPoint, and tools used for journal publication.

2-D Plotting
O-Matrix supports all 2-d plot types that are typically required for scientific and engineering analysis; all of which can be controlled to create highly-specialized plots.

• Line and Scatter plots with single or multiple curves

• Histograms

• Vector Plots

• Bar, Stair, and Bubble charts

• Smith charts and Polar Plots

• Filter Response Plots

• Animations

3-D Plotting and Visualizing Multi-dimensional Data
O-Matrix provides numerous functions for plotting single and multiple variables in 3-D.

• Contour plots

• Stacked contours, with or without hidden line removal

• Mesh and Surface plots

• 3-D Line and symbol plots

Implementing Algorithms in O-Matrix

O-Matrix provides a simple-to-use, high-performance interpreted language. Commands can be entered directly at the command line and executed as you enter them, providing immediate results or commands and user-defined functions can be entered in text-based files. The syntax of the O-Matrix language is a hybrid of BASIC, and other matrix languages providing a very easy-to-learn and compact notation where algorithms are the same as the mathematics they represent.

The O-Matrix language and run-time environment facilitate both rapid, interactive visual data analysis and the construction of large, sophisticated applications. Typical end user solutions range from a few commands entered at the command prompt to thousands of lines of code spanning many files.

Data Access and Manipulation with O-Matrix

O-Matrix provides extensive capabilities for working with data from files, applications, devices, and databases. Directly load data from formats such as Excel, text files, HDF, WAV files, and PLT files. Low-level utilities are provided to enable importing and creation of arbitrary ASCII or binary data. Using the O-Matrix OLE/COM Automation functions you can leverage the data import and export capabilities of other applications. O-Matrix can link with compiled objects from languages such as C/C++ and FORTRAN to enable the use of custom data input and output routines from within the O-Matrix language.

The O-Matrix data access and manipulation routines are highly optimized and can efficiently work with data sets that contain hundreds of thousands of data points and using many megabytes. The import of a multi-megabyte file in O-Matrix takes a fraction of the time needed by Excel, and is typically much quicker than the same algorithm implemented in a compiled language.

O-Matrix excels at manipulating and formatting data. Numeric and textual data can be re-formatted as it is loaded or manipulated after loading. Flexible routines are provided to enable sophisticated formatting and manipulation of various data formats.

Building Graphical User Interfaces with O-Matrix

O-Matrix includes functions for creating custom GUIs. Design dialogs with buttons, popups, checkboxes, tables, bitmap display, grid tables, and other common Windows controls. Interfaces can be developed in O-Matrix in a fraction of the time of compiled languages, and provide much better performance than typical interpreted solutions. Using O-Matrix GUI building capabilities and The O-Matrix Development Kit users can rapidly develop technical computing solutions that can be distributed royalty-free.
