DataFitX 2.0

NonlinearRegression and MultipleNonlinearRegression objects provide methods and procedures for defining regression models with up to 100 fitting parameters and performing nonlinear regression on data containing up to 50 independent variables. The CubicSpline object performs cubic spline interpolation on 2-dimensional data. These objects provide properties and methods that return results for the fitting parameters, as well as detailed statistical

Nonlinear Image Resizing Tool 1.0: Resize images between aspect ratios while preserving the center of the image
Nonlinear Image Resizing Tool 1.0

This tool is used to perform a nonlinear resize (or "warp") of an image. By warping, you can resize an image such that the objects in the center of an image remain clear and undistorted, and distortion occurs near the edges of the image. This tool is useful for situations where you need to convert an image from one aspect ratio to another without cropping.

Ordinary Differential Equations 1.00: Solves boundary-value problems involving ordinary differential equations
Ordinary Differential Equations 1.00

Solves boundary-value or initial-value problems involving nonlinear or linear ordinary differential equations of any order, or systems of such. The conditions may also be linear or nonlinear. The solution will be a finite power or trigonometric series. You have one-click control of the graph with zooming, panning, centering, etc. The solution may be studied by the POWER & TRIG SERIES program to find roots, extrema, derivatives, integral, graph.

  • iLOOKABOUT Corp. Announces Second Quarter ResultsLONDON, ONTARIO--(Marketwire - Aug. 20, 2008) - iLOOKABOUT Corp. ("iLOOKABOUT" or "the Company") (TSX VENTURE:ILA) announced the release of its second quarter results. The Company reported revenue of $185,730 and $366,433 for the three months and six months ended June 30, 2008, respectively. To assist in forecasting future financial resources, the Company monitors revenue backlog. The Company defines revenue backlog as the estimated revenue attributable to the uncompleted portion of signed sales agreements for which future collection is probable, selling price is fixed and determinable, and there is no reason to believe that the Company will be unable to deliver the contracted service. To the extent revenue derived from these sales agreements is recognized in future periods for financial reporting purposes, this recognized revenue amount is then removed from the revenue backlog. The revenue backlog does not include that portion of revenue associated with sales agreements extending b
