Calcpad is free software for mathematical and engineering calculations. It represents a flexible and modern programmable calculator with Html report generator. It is simple and easy to use, but it also includes many advanced features:

• real and complex numbers;
• units of measurement (SI, Imperial and USCS);
• vectors and matrices: rectangular, symmetric, column, diagonal, upper/lower triangular;
• custom variables and units;
• built-in library with common math functions;
• vectors and matrix functions:
  • data functions: search, lookup, sort, count, etc.;
  • aggregate functions: min, max, sum, sumsq, srss, average, product (geometric) mean, etc.;
  • math functions: norm, condition, determinant, rank, trace, transpose, adjugate and cofactor, inverse, factorization (cholesky, ldlt, lu, qr and svd), eigenvalues/vectors and linear systems of equations;
• custom functions of multiple parameters f(x; y; z; …);
• powerful numerical methods for root and extremum finding, numerical integration and differentiation;
• finite sum, product and iteration procedures;
• modules, macros and string variables;
• program flow control with conditions and loops;
• "titles" and 'text' comments in quotes;
• support for Html and CSS in comments for rich formatting;
• function plotting, images, tables, parametric SVG drawings, etc.;
• automatic generation of Html forms for data input;
• professional looking Html reports for viewing printing;
• export to Word (*.docx) and PDF documents;
• variable substitution and smart rounding of numbers;
• output visibility control and content folding;
• support for plain text (*.txt, *.cpd) and binary (*.cpdz) file formats.

This software is developed using the C# programming language and the latest computer technologies. It automatically parses the input, substitutes the variables, calculates the expressions and displays the output. All results are sent to a professional looking Html report for viewing and printing.
