About Calcpad
Calcpad is professional 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 in different bases;
- units of measurement (SI, Imperial and USCS);
- vectors and matrices: rectangular, symmetric, column, diagonal, upper/lower triangular;
- custom variables and units of measurement;
- string and table data types;
- built-in library with common math, special, statistical, financial and string manipulation functions;
-
vectors and matrix functions:
- data functions: search, lookup, sort, count, etc.;
- aggregate functions: min, max, sum, sumsq, srss, average (mean), product, geometric mean (geomean), etc.;
- math functions: norm, condition, determinant, rank, trace, transpose, adjugate and cofactor, inverse, factorization (Cholesky, ldlt, lu, qr and svd), eigenvalues/vectors, linear systems of equations, fast Fourier transforms, etc.;
- 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, macro functions and macro variables;
- reading and writing data from/to text, CSV and Excel files;
- program flow control with conditions and loops;
- 'text' comments in single quotes and '"headings;
- support for Html, CSS and Markdown 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 and 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 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.
