Questions tagged [polynomials]

In mathematics, a polynomial is an expression consisting of variables (or indeterminates) and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents.

In mathematics, a polynomial is an expression consisting of variables (or indeterminates) and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents.

An example of a polynomial of a single indeterminate (or variable), x, is x2 − 4x + 7, which is a quadratic polynomial.

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 and algebraic varieties, central concepts in algebra and algebraic geometry.

polynomial fitting on spectral data

I want to fit a polynomial function (max. 3rd order) on each raster cell over all my spectral bands (Landsat 1-7) creating a new raster(stack) representing the coefficients. I got my data (including NA values) in a stack with 6 Layer (Landsat Band…

Normalizing a Polynom

I need to read in a Polynom and transform it into normalized form. For example I read in 4*x * (x^2 + 4x + 3) and it has to be transformed to 4*x^3 + 16*x^2 + 12*x. Is there some tricky algorithm for it or do I have to think of something myself.…

Polynominal with doubly linked list - pointer problem

I made some polynomial code with a doubly-linked list. for example, if you write 1 and 2 then 1 is a degree and 2 is coefficient. 1x^2 insert to doubly linked list. the problem is that when I check my code, the Node head->degree is changing. if I…

How to find all the terms of a polynomial that contain a specific variable in Matlab?

Let say that we have the polynomial f=a^2*b+b^2*c+c*d. I would like to know if, in Matlab, I could find all the terms of f that contain specific polynomials of variables a, b, c and d. For example, if I have a polynomial of variable c, that is…
