Annoucement : smib0.29 release
Posted:
Nov 2, 2012 12:09 PM


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/ Homepage at : http://smib.sourceforge.net/
In this version :  odesolve : ordinary differential equation solver (for first order  using dsolve, and second order if coefficients are constant)  dsolve uses antider instead of integral (calling a smib program in the smib kernel (in C language))  Syracuze conjecture (dynamic allocation of arrays)  Mertens function & Redheffer matrix
V 0.28 :  some optimizations in generalized stochastic differential equation  Mertens fonction  new documentation
V 0.27 :  quantum mechanic using smib
V 0.26 :  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 Wnowritestrings 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  nonlinear 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 (EulerMurayama & 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=(x1)*(x+1)/(x1), 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.
