Q: I am new to integrated math packages and interpreters, where's the best place to start?
A: Reviewing the getting started chapter and then working through the tutorial will give you a working knowledge of the O-Matrix environment and language.

Q: I am familiar with tools like Matlab or Mathematica, where's the best place to start?
A: Working through the tutorial and then reviewing the mlmode chapter and O-Matrix/Matlab Function List will give you a working knowledge of O-Matrix and help migrate your knowledge and applications from Matlab.

Q: What are O-Matrix strengths?
A: O-Matrix is the fastest executing, least expensive commercial data analysis environment available. O-Matrix provides a matrix language with constructs and capabilities not found in typical interpreters and the library of functions included with the base package includes a broad range of functions that typically require purchased add-ons with other packages. See the Why Users Are Choosing O-Matrix page for a comparison with Matlab specifically.

Q: What is the best way to find a function by name or keywords?
A: Enter the function name or keywords in the search tool above or go to the index page.

Q: Can I purchase a printed version of the manual?
A: As part of our efforts to keep O-Matrix affordable we do not print the manual. A PDF of the manual suitable for printing is available on the technical support page.

Q: O-Matrix is very inexpensive compared to some of the alternatives, do I still get support?
A: O-Matrix comes with complete tech support. See the technical support center for obtaining help.

Q: Can O-Matrix run Matlab scripts?
A: The O-Matrix environment does support the execution of basic MATLAB scripts and functions in addition to O-Matrix scripts and functions. O-Matrix can also run some scripts that are written completely in the MATLAB syntax. In general, MATLAB scripts that don't use GUI building, plotting, or cell array structures are compatible.

Q: Is O-Matrix available for UNIX, Linux, and Mac?
A: As of version 6.4, O-Matrix is only available for Windows. Numerous customers are using O-Matrix under various Windows emulators on Linux and Mac.

Q: What is the O-Matrix Development Kit and how is it different from O-Matrix?
A: The O-Matrix Development Kit provides an easy to use, efficient, and free method to distribute O-Matrix applications. Applications built with The O-Matrix Development Kit can range from simple scripts to turnkey systems and products. Visit http://www.omatrix.com/omrte.html to learn more. The O-Matrix Development Kit is licensed separately and requires a current valid O-Matrix license.

Q: What is the O-Matrix Tecplot link?
A: The O-Matrix Tecplot link is a set of functions provided with O-Matrix that enables users to create plots in Tecplot of O-Matrix results, transfer data to and from Tecplot, and to automate Tecplot with the O-Matrix language.

Q: How can O-Matrix run so much faster than the alternatives?
A: O-Matrix has been built using highly optimized C/C++, FORTRAN, and assembly code to provide optimal execution performance. Many functions are implemented with proprietary algorithms and code is written using advanced hardware features such as SIMD technology, multi-core capabilities, and code vectorization. The linear algebra routines in O-Matrix are based on the algorithms from BLAS, LINPACK, and LAPACK to provide robust, accurate solutions.

Q: How many functions does O-Matrix have?
A: O-Matrix has about 1000 functions available to end users, but this number is not necessarily a metric of capability as many functions provide a broad range of functionality. About 70% of the O-Matrix functions are provided as script files, that is user readable, text-based files. The other 30% of the functions are built into the O-Matrix executable.

Q: What industries, or types of applications use O-Matrix?
A: O-Matrix is used in diverse industries, especially those that require the highest levels of execution performance available. The organizations using O-Matrix most frequently include: Earth and ocean sciences, aerospace and defense, financial services, utilities, and energy.

Q: Is my O-Matrix license time limited, or do I have to purchase software maintenance?
A: We do not sell software maintenance. O-Matrix licenses are perpetual. When new releases are available they are typically made available for about %40 of the original purchase price.
