Polynomial Function DefinitionPolynomial functions are expressions that may contain variables of varying degrees, coefficients, positive exponents, and constants. Here are some examples of polynomial functions.f(x) = 3x2 - 5 g(x) = -7x3 + (1/2) x - 7 h(x) = 3x4 + 7x3 - 12x2...
A more simple definition of a homogeneous polynomial is that that the sum of the exponents of the variables is the same for every term. For example, x3+ y3= z3or x2y3= z5). The most famous example of a homogeneous polynomial is thePythagorean theoremx2+ y2= z2. The expression x5+...
Definition 9.1.1. A function f defined by f(x) = mx + b for some constants m and b is called a linear function. The number m is called the slope of the line, and b is the y-intercept. The number b is called the y-intercept because f(0) = b. This means that when x = 0...
Definition A local maximum or local minimum at x=ax=a (sometimes called the relative maximum or minimum, respectively) is the output at the highest or lowest point on the graph in an open interval around x=a.x=a. If a function has a local maximum at a,a, then f(a)≥f(x)f(a)...

Quite simple examples of local basis functions may be in the form of a look-up table (LUT) in which elements of the table only act upon its own specific region of the envelope. Another example which allows for switching between local cross-terms in the memory-space, is the so-called vec...

If M(A) is semi-simple, then M(A) is isomorphic to a product of full matrix rings over commutative fields. If the Jacobson radical, J, of M(A) is a maximal ideal, then M(A)/J is isomorphic to a full matrix ring over a commutative field.;The definition and basic properties of ...
We can see this in a simple example with the function f(x)=11+25x2. This function seems to be fairly innocuous, but it tortures polynomial interpolation. We will look at 5th and 7th degree polynomials. Using our Lagrange polynomial function defined above, we produce the interpolating ...
