| 1 | + | ## About | |
| 2 | + | ||
| 3 | + | LMath is a mathematical library for Free Pascal (FPC) and Lazarus. It's a further development of [[DMath]] from Jean Debord. It is entirely written in Pascal and does not depend on external libraries. | |
| 4 | + | ||
| 5 | + | 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. | |

| 11 | + | ## Changes from DMath | |
| 12 | + | ||
| 13 | + | - Naming of packages and units made more systematic. Now names of all units begin from u (for example, uTypes), while names of all packages begin from lm (for example, lmMathUtil). Hence, you will probably change Requirements in your project inspector. | |
| 14 | + | - Units uVectorHelper, uVecUtils, uVecFunc and uVecPrn in lmMathUtil package define several handy functions for work with arrays. | |
| 15 | + | - Unit uMatrix in lmLineAlgebra defines several general operations over vectors and matrices. | |
| 16 | + | - COBYLA algorithm (Constrained Optimization by Linear Approximation, M. Powell) for tasks of constrained optimization included in lmOptimum package, unit uCobyla. | |
| 17 | + | - Procedure for constrained non-linear regression ConstrNLFit in the unit uConstrLNFit which uses COBYLA algorithm included in lmRegression package. | |
| 18 | + | - Procedure LinProgSolve in the unit uLinSimplex, package lmOptimum implements simplex method for solution of linear programming problems. | |
| 19 | + | - Unit uintPoints in lmGenMath package defines operators over TIntPoint, similar to uRealPoints. | |
| 20 | + | - Unit uUnitsFormat in lmMathUtils package allows now using of long prefixes (for example, "pico") along with short ("p") ones. | |
