An n-bit LUT can encode any n-input Boolean function by storing the truth table of the function in the LUT. This is an efficient way of encoding Boolean logic functions, and LUTs with 4-6 bits of input are in fact the key component of modern field-programmable gate arrays (FPGAs) which provide reconfigurable hardware logic capabilities.
Use of a user-defined function sq(x) in Microsoft Excel. The named variables x & y are identified in the Name Manager. The function sq is introduced using the Visual Basic editor supplied with Excel. Subroutine in Excel calculates the square of named column variable x read from the spreadsheet, and writes it into the named column variable y.
In mathematics and computer science, a higher-order function (HOF) is a function that does at least one of the following: takes one or more functions as arguments (i.e. a procedural parameter, which is a parameter of a procedure that is itself a procedure), returns a function or value as its result. All other functions are first-order functions.
LANPAR, available in 1969, [10] was the first electronic spreadsheet on mainframe and time sharing computers. LANPAR was an acronym: LANguage for Programming Arrays at Random. [10] VisiCalc (1979) was the first electronic spreadsheet on a microcomputer, [11] and it helped turn the Apple II into a popular and widely used personal computer.
When returning a function, we are in fact returning its closure. In the C example any local variables captured by the closure will go out of scope once we return from the function that builds the closure. Forcing the closure at a later point will result in undefined behaviour, possibly corrupting the stack. This is known as the upwards funarg ...
There is an explicit function f that has been proved to be one-way, if and only if one-way functions exist. [5] In other words, if any function is one-way, then so is f . Since this function was the first combinatorial complete one-way function to be demonstrated, it is known as the "universal one-way function".
He claims that Friday is the day he catches up on "personal stuff" like checking his inbox, returning e-mails, and writing his weekly thank you notes. He explains that he is running behind and asks the audience if they would not mind if he took time out of the show to write them, and asks James Poyser to play some accompanying music (a sped-up ...
The most common example of a non-elimination match is the Three-Way match (also known as a Triple Threat match in WWE, Triangle match in WCW and Three-Way Dance in ECW), in which three wrestlers compete under standard rules with the first competitor to achieve a pinfall or submission being declared the winner. Triple Threat matches are fought ...
