Polynomial & Math Calculator: Mates8

Mathematical expression parser and evaluator

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

Mates8 features:

» Basic arithmetic and polynomial operations (-,+,*,/,^,%), including GCD
» finds polynomials roots, of real or complex coefficients, 
» does multivariable polynomial division,
» Lagrangian interpolation and
» basic matrix operations (-,+,*,/,^).
» May obtain the inverse matrix, 
» cofactor,
» adjoint,
» transpose matrix,
» echelon form,
» Jordan form,
» eigenvalues,
» eigenvectors, 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;
» approximates the exponential matrix (e.g. exp(1,cos(x)|0,1)=(2.718..,2.718...*cos(x)|0,2.718...))
» Resolves linear, when compatible and determinate or indeterminate,
» 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.
» Solve some ordinary first order differential equations with or without specifying the initial condition.
» Approximates first order diff. eqs. by Euler's method specifying the initial condition.

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

Windipoles

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 version is v4.8.11.zip.

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.
