Mat Posted January 24, 2010 Share Posted January 24, 2010 (edited) I have a plan for a large extension to my quadratic solver... And heres the work so far!In mathematics, a polynomial is an expression of finite length constructed from variables (also known as indeterminates) and constants, using only the operations of addition, subtraction, multiplication, and non-negative, whole-number exponents. For example, x2 − 4x + 7 is a polynomial, but x2 − 4/x + 7x3/2 is not, because its second term involves division by the variable x and because its third term contains an exponent that is not a whole number.Polynomials appear in a wide variety of areas of mathematics and science. For example, they are used to form polynomial equations, which encode a wide range of problems, from elementary word problems to complicated problems in the sciences; they are used to define polynomial functions, which appear in settings ranging from basic chemistry and physics to economics and social science; they are used in calculus and numerical analysis to approximate other functions. In advanced mathematics, polynomials are used to construct polynomial rings, a central concept in abstract algebra and algebraic geometry.Current functions:;_Polynomial_Add;_Polynomial_Check;_Polynomial_Div;_Polynomial_Factorise;_Polynomial_Format;_Polynomial_GetMaxIndex;_Polynomial_GetValues;_Polynomial_IsRoot;_Polynomial_Mul;_Polynomial_Sort;_Polynomial_Sub;_Polynomial_ToHtml;_Polynomial_ToRtfDownload link: Polynomial.zip(NB: Not all have examples atm)Mat Edited January 26, 2010 by Mat AutoIt Project Listing Link to comment Share on other sites More sharing options...

DJKMan Posted January 26, 2010 Share Posted January 26, 2010 It is an excellent start. However, I found a minor problem. I know it has not been coded yet but I thought I would point it out. 3x^(5+1x)+3 returns "" This is still a great script and I look forward to updates.

Interesting idea, it would somewhat cripple the way the script works with arrays though...must be in the form ax^2+bx+c, ax^3+bx^2+cx+d etc. depending on the order of the polynomial. I could try and get the regexp pattern to match brackets if they are used... but that will be quite difficult as i'm now looking at functions for expanding a factorised equation etc, and so depend on bracket detection.I have already written several more functions for this so no doubt it will be updated soon.Mat AutoIt Project Listing Link to comment Share on other sites More sharing options...

Mat Posted January 26, 2010 Author Share Posted January 26, 2010 Updated!!! Lots of functions added: * _Polynomial_Add * _Polynomial_Div * _Polynomial_Factorise * _Polynomial_IsRoot * _Polynomial_Mul * _Polynomial_Sub Factorise being the most important of these, and also the one that ended up the best. Before (in the quadratic solver) I was comparing all the factors of a and b to test, When in fact you only need to test the factors of C. The div function also worked out pretty well, and I managed to get it working first guessing at what to do... Mat AutoIt Project Listing Link to comment Share on other sites More sharing options...
