Polynomial & Math Calculator: Mates8

Mathematical expression parser and evaluator

  Mates8 is the downloadable version of the Online Polynomial and Scientific Calculator.

  Mates8 does basic math and polynomial operations (-,+,*,/,^,%), finds polynomials roots, of real or complex coefficients, multivariable polynomial division, Lagrangian interpolation and basic matrix operations (-,+,*,/,^). May obtain the inverse, cofactor, adjoint and transpose matrix and the determinant of an invertible matrix of real, complex, polynomial or expression entries. Performs derivatives using Euler's notation, e.g.: Dx(sin(x)); Jacobian; and resolves linear, when compatible and determinate, as non linear system of equations.

  Also is capable of bounded definite integrals, inmediate, trigonometric or partial fractions integration -quotients of polynomials integration- and integration by parts.

  You may find examples in Predefined/Examples menu option of the application's form.

  Mates8 intends to be an improved version of previous Mates2-Mates6 calculators.

Windipoles is a free passive filter simulator. It is a Windows .NET executable, so no software installation is required and works in Win32 and Win64 machines. It enables design, analysis, optimizations and plots, all graphically. While component values are changed, graphic windows are updated instantly. Graphics may show, overlapped, more than one network for comparing purposes. Also, synthesizes Butterworth, Bessel, Chebyshev (types I & II), and Cauer (elliptic) filters. Windipoles has a help .chm file. Also it does not connect to internet and needs no special rights to execute. Current beta version is 4.7.27.

PdfSharp and Excel reporting sample

A VStudio Express 2013 for Web project

The .vb file names ending in "pdf" invoke pdfsharp.dll. The ones ending in "xls" correspond to the "pdf" ones with same sufix and the output format is an Excel Workbook. Note there are two font files (.ttf) to ensure the .pdf file contains embedded the required font. You'll need to change the paths, the web reference, fields and anything else required to your needs.
