What is Calcul?
Calcul is an open-source mathematical computation suite engineered to handle fundamental calculations in linear algebra, physical unit conversion, and statistical distribution theory. It serves as a unified utility for students, software engineers, and data analysts who require precise mathematical operations without loading heavy desktop computation packages like MATLAB or Wolfram Mathematica. The tool accepts formatted numerical arrays, scalar parameters, and measurement unit definitions as inputs, then evaluates them using standard linear algebra and statistical formulas. For example, when supplied with a 3x3 input matrix, Calcul computes explicit matrix properties such as the determinant, trace, and inverse matrix, returning structured numerical outputs alongside intermediate derivation steps. First, it performs primary linear algebra operations, including matrix multiplication, determinant evaluation, rank determination, and LU decomposition. Second, it implements a physical unit conversion system covering standard SI units, imperial measurements, and specialized engineering dimensions like dynamic viscosity (Pascal-seconds to centipoise) and thermal conductivity. Third, it calculates probability density functions (PDF) and cumulative distribution functions (CDF) for continuous and discrete distributions, including normal, Poisson, binomial, and chi-square distributions. Compared to generic desktop calculators, Calcul provides scientific depth by maintaining exact 64-bit floating-point precision throughout calculation pipelines. Unlike closed-source online conversion scripts, its open-source codebase allows developers to audit the underlying algorithms used for floating-point arithmetic and statistical approximations directly on GitHub.
