...It is entirely written in Pascal and does not depend on external libraries. LMath provides routines and demo programs for numerical analysis, including mathematical functions, probabilities, matrices, optimization, linear and nonlinear equations, integration, Fast Fourier Transform, random numbers, curve fitting, statistics and graphics. It is organized s set of lazarus packages which makes it easily extensible and helps to include only really needed features in your project.

Integer and fractional elements are allowed, but not floating point numbers. Matrices (or their elements) and systems of linear equations can be also generated by the app, to practice with operations and propieties. The app calculates the matrix range, determiner of square matrices, traspose, inverse of inversible matrices (that is, square matrices with non zero determiner), the matrix of adjuncts, the forms of Gauss and Gauss-Jordan. It allows submatrices extraction by selection of rows and columns. ...
