smib is a mosaic of FORTH and LISP, C Sauce and an experimental programming language in mathematics.
Some experimental fields :
- Arithmetic & number theory
- Differential geometry
- Numerical analysis
- Probability & statistics.

Download at : http://sourceforge.net/projects/smib/

In this version :
- quaternions
- bug corrections

V 0.25 :
- antiderivative v2 : new version of defint too
- perfect number & harmonic mean of divisors
- bug corrections
- rational fonction & decomposition
- antiderivative
- bug corrections

V 0.23 :
- Some polynomial algebra :
* Bezout identity (extended greater divisor)
* squarefree factorization
* resultant
* discriminant

V 0.22 :
- law of large numbers & central limit theorem
- some simplifications in hyperbolic trigonometry
- almost all warnings suppressed (using -Wno-write-strings option)

V 0.21 :
- generalized stochastic differential equation (not only with brownian motion): mean and variance computation
- Stratonovitch stochastic integral with brownian motion
- bug correction.

V 0.20 :
- stochastic differential equation : mean and variance computation
- non-linear least squares approximation.

V 0.19 :
- Lagrange interpolation using Newton polynomials
- sample applied to quantile and median.

V 0.18 :
- complex analysis : complex path, complex path integral, complex path index, number of singularities
- bug fix: simplification of expressions, numerical evaluation.

V 0.17 :
- derivation of samples (integer & fractional)
- bug correction.

V 0.16 :
- Numerical application to special functions : Bessel functions, Hankel functions & Airy functions
- Some new example applied to differential geometry, probability & statistic.

V 0.15 :
- tensor calculus finally documented

V 0.14 :
- numerical analysis :
- fractionnal derivative
- new version of Euler scheme : ODE and coupled ODEs are treated by one program
- probability & statistic :
- gaussian random nuber
- new version of brownian motion
- bugs correction.


V 0.13 :
- numerical analysis :
- first order differential equation
- system of two first order differential equations
(using Euler scheme).

- probability & statistic :
- quantile & median
- stochastic differential equation (Euler-Murayama & Milstein schemes)

- new documentation.


V 0.12 :
- probality & statistic :
- expected value
- variance
- standard deviation
- skewness
- kurtosis
- least square line

- differential geometry :
- planar curves
- 3D curves
- theory of surfaces using Gauss approach

- improvement :
- simplify (if A=(x-1)*(x+1)/(x-1), simplify(A) returns : 1 + x)
- numint (if simpsonint = 1, Simpson scheme is used, else Gauss scheme is used), for probability, it is a good idea to set simsonint to 1.
