A recent Math-Forum post by pbillet from Paris didn't make it to the Italian Aioe.org NNTP server that a number of people are relying on; this is rectified below. One of the posters affected by these failures should perhaps inform the Math-Forum administrators that their outgoing connection to usenet is unsatisfactory.
Annoucement : smib-0.21 release Posted: Aug 27, 2011 1:48 AM
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.
In this version : - 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.
