The Bluebit .NET Matrix Library provides classes for object-oriented linear algebra in the .NET platform. It can be used to solve systems of simultaneous linear equations, least-squares solutions of linear systems of equations, eigenvalues and eigenvectors problems, and singular value problems. Also provided are the associated matrix factorizations such as Eigen, LQ, LU, Cholesky, QR, SVD. Both real and complex matrices are supported.

The most powerful Sci/Eng calculator for Windows. Expression evaluation, 18 digits of precision, variables, >100 functions, unit conversion, polynomial roots, interpolation, polynomial regression, linear algebra, numerical integration and differentiation, systems of linear, non-linear and differential equations, multi-argument functon optimization and fitting, curve, point and histogram graphs, statistical operations, computer math (bin/oct/hex).

Build linear measurement skills, with English and metric rulers. This multimedia program uses the Microsoft Agent Peedy, a parrot character. Printed worksheets and tests can also be generated.

This is a demo of a SDK witch allows you to include linear, PDF417 and DataMatrix barcode recognition features in your own programs. It reads black-white, gray and color TIFF, PNG, JPG and BMP images and detects the most important linear barcode types and PDF417 and DataMatrix symbols. The recognition is customizable ( search area, barcode types, etc).

Perspective Pilot is designed for correction of linear distortions of a perspective appeared on photographs. You should only set a vertical or horizontal axle and the software will do the rest. The program also allows adjusting the angle of the horizon line by setting it as the horizontal line. The redundant edges of a photograph will be automatically cropped in the final stage of image processing.

37988 algebraic equations with solutions and test authoring tools. Considered are problems from basic to advanced - linear, quadratic, biquadratic, reciprocal, cubic and complex fractional equations. Easy-to-use test authoring options enable selecting problems by complexity and solution methods and creating math tests, homeworks, quizzes and exams of varied complexity. The program generates three variant tests around a constructed example

Easy-to-use test authoring options enable selecting problems by complexity and solution methods and creating math tests, homeworks, quizzes and exams of varied complexity. The program generates 30 variant tests around a constructed example.

Calculate the Product or Service Mix that maximizes overall profit. Up to six unique outputs can be handled with ten specific resource inputs. Outputs are the result of any process including manufactured items and the provision of services. Resources are anything needed to produce or provide the output i.e materials, labor, machine time etc. The model considers the resource demand, profit contribution and any minimum or maximum requirements.

Linear programming environment that incorporates large-scale linear programs solver and easy, intuitive graphical user interface to specify, import and solve any type of constrained optimization problems arising in various industrial, financial and educational areas. Optimization problems are stated as linear programs with UNLIMITED number of decision variables and constraints.
