	Characteristic function - Wikipedia, the free encyclopedia
		The indicator function of a subset A of a set B is the function with domain B, whose value is 1 at each point in A and 0 at each point that is in B but not in A.
		The characteristic function is closely related to the Fourier transform: the characteristic function of a distribution with density function f is proportional to the inverse Fourier transform of f.
		Characteristic functions are used in the most frequently seen proof of the central limit theorem.

	Indicator function - Wikipedia, the free encyclopedia
		In the mathematical subfield of set theory, the indicator function, or characteristic function, is a function defined on a set X which is used to indicate membership of an element in a subset A of X.
		As suggested by the previous example, the indicator function is a useful notational device in combinatorics.
		The indicator function of a subset A of a set X is a function

	Spatial Correlation and Indicator Kriging
		For a given threshold value, the indicator transform function assigns a value of 1 for data less than the threshold and 0 if it is greater.
		Indicator kriging relies on models that quantify the spatial correlation among data values under the indicator transform.
		In indicator kriging, the range of data values may be partitioned by a series of threshold values.

		The indicator variogram is calculated using the indicators of the data from a particular cutoff.
		The median indicator variogram is defined to be the variogram of the indicators when 50% of the indicator data is set equal to one (mean=0.50, variance=0.25).
		Indicator variograms are defined for a number of different cutoff values using the indicator data found for each cutoff.

	Markov chain - Wikipedia, the free encyclopedia
		Furthermore, the equivalence of averages also holds if f is the indicator function on some subset A of the state space.
		A stationary distribution is an eigenfunction of the conditional distribution function, associated with the eigenvalue 1.
		In particular, this holds for f equal to the identity function.

		This function returns the amount of bars by the moment of the preceding launch of the indicator, i.e., the amount of bars having already been calculated (potentially, if there were no errors or early termination during the preceding launch) which do not need any recalculation.
		The "IndicatorBuffers" function specifies the amount of buffers to be used in indicator claculation.
		The "SetIndexLabel" function sets the name to be displayed in tool tips and in data window along with the corresponding value (the "ValueN" is set by default, where N is the number of the index array).

	Autobiography of Patrick Suppes, p. 10
		The move from events to extended indicator functions is especially interesting philosophically, because the choice of the right objects to consider in formulating a given theory is, more often than I originally thought, mistaken in first efforts and, as these first efforts become crystallized and familiar, difficult to move away from.
		To each event there is a corresponding indicator function for that event, with the indicator function having the value one when a possible outcome lies in the event and the outcome zero otherwise—as is apparent, in this standard formulation events are sets of possible outcomes, that is, sets of points in the probability space.
		However, if we replace the event A by its indicator function Ac, then AcB is just the indicator function restricted to the set B, and we can express in a simple and natural way the operation of function addition of two such partial functions having the same domain.

	Dial Indicator Instructions
		NOTE: The dial indicator's function is to measure a knife from end to end insuring that it is completely level the length of the cutting surface.
		Rotate the cutterhead or slide the magnetic base unit so that while the dial indicator tip is in contact with the cutterhead, it gently slides up on the edge of the newly installed knives (See your owner's manual for proper knife installation instructions).
		Place the assembled unit on the out-feed table of your machine with the tip of the dial indicator touching top dead center of your cutter head making sure there is a slight amount of pressure on the indicator tip.

	Indicators as Functions
		Formula indicators designed to behave as functions should be called only from within formula definitions, but they can accept variable data expressions where parameters are specified in their own definitions.
		However, formula indicators can be designed to look like either indicators, which perform calculations on predefined data, or like functions, which calculate using data passed to them in their argument list.
		In each indicator, parm1 is replaced by the data array in the first argument, while parm2 is replaced by the scalar value in the second argument.

	Features of Writing Custom Indicators and User Functions
		The values of the variables in the function of custom indicator calculation, and the data arrays with the results of custom indicator calculation will be initialized at the first run of the indicator, and at the period or instrument change at the chart.
		As soon as the indicator runs for the first time the check of the first variable will be conducted and the value of the loopbegin variable will be established on the assumption that the cycle would run from the data beginning.
		If the indicator is shown in a separate window and the limiting values of the minimum and/or maximum are known beforehand, these limiting values can be defined to accelerate the displaying and, in some case, to make the displaying more beautiful (this especially concerns histograms).

	The Finite Element Method (Partial Differential Equation Toolbox)
		The error indicator function used in the toolbox is an element-wise estimate of the contribution, based on the work of C. Johnson et al.
		This bound is turned into an element-wise error indicator function E(K) for element K by summing the contributions from its edges.
		The theory of adaptive schemes makes use of a priori bounds for solutions in terms of the source function f.

	4. Exception Handling
		When a function must fail because some function it called failed, it generally doesn't set the error indicator; the function it called already set it.
		Most functions don't clear this on success, but will set it to indicate the cause of the error on failure.
		This is a convenience function to raise an exception when a C library function has returned an error and set the C variable

	fwrap
		The ordering of fwrapped functions is specified as follows: If an fwrapper of the same indicator was present on this primary-function before the call, then the order is not changed; the fwrap call simply replaces that fwrapper with the specified fwrap-function wherever it was previously.
		If no fwrapper of the same indicator yet existed on this primary-function, then a new fwrapper is established as the outermost fwrapper, i.e.
		indicator may be any object for which eq comparisons are appropriate, as if with getf.
