  2. Parameter (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Parameter_(computer...

    An output parameter, also known as an out parameter or return parameter, is a parameter used for output, rather than the more usual use for input. Using call by reference parameters, or call by value parameters where the value is a reference, as output parameters is an idiom in some languages, notably C and C++, [ b ] while other languages have ...

  3. Argument of a function - Wikipedia

    en.wikipedia.org/wiki/Argument_of_a_function

    In mathematics, an argument of a function is a value provided to obtain the function's result. It is also called an independent variable. [1] For example, the binary function (,) = + has two arguments, and , in an ordered pair (,).

  4. Parameter identification problem - Wikipedia

    en.wikipedia.org/wiki/Parameter_identification...

    Here both equations are identified if c and d are nonzero. Note that this is the structural form of the model, showing the relations between the Q and P. The reduced form however can be identified easily. Fisher points out that this problem is fundamental to the model, and not a matter of statistical estimation:

  5. Identifiability - Wikipedia

    en.wikipedia.org/wiki/Identifiability

    If the distributions are defined in terms of the probability density functions (pdfs), then two pdfs should be considered distinct only if they differ on a set of non-zero measure (for example two functions ƒ 1 (x) = 1 0 ≤ x < 1 and ƒ 2 (x) = 1 0 ≤ x ≤ 1 differ only at a single point x = 1 — a set of measure zero — and thus cannot ...

  6. Parameter - Wikipedia

    en.wikipedia.org/wiki/Parameter

    In computer programming, two notions of parameter are commonly used, and are referred to as parameters and arguments—or more formally as a formal parameter and an actual parameter. For example, in the definition of a function such as y = f(x) = x + 2, x is the formal parameter (the parameter) of the defined function.

  7. Variable (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Variable_(mathematics)

    A parameter is a quantity (usually a number) which is a part of the input of a problem, and remains constant during the whole solution of this problem. For example, in mechanics the mass and the size of a solid body are parameters for the study of its movement. In computer science, parameter has a different meaning and denotes an argument of a ...

  8. Computational problem - Wikipedia

    en.wikipedia.org/wiki/Computational_problem

    For example, in the factoring problem, the instances are the integers n, and solutions are prime numbers p that are the nontrivial prime factors of n. An example of a computational problem without a solution is the Halting problem. Computational problems are one of the main objects of study in theoretical computer science.

  9. Numerical continuation - Wikipedia

    en.wikipedia.org/wiki/Numerical_continuation

    Natural parameter continuation is a very simple adaptation of the iterative solver to a parametrized problem. The solution at one value of λ {\displaystyle \lambda } is used as the initial guess for the solution at λ + Δ λ {\displaystyle \lambda +\Delta \lambda } .
