alcpad is professional software for mathematical and engineering calculations. It uses a simple, intuitive programming language, so you can build complex calculation programs without any special programming skills. Just enter the formulas and the text of your calculation report, and you’ll get the results as a professionally formatted HTML or Word document. 

Calcpad is very simple and easy to use, but it also very powerful and includes a lot of 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;
