In the Deutsch–Jozsa problem, we are given a black box quantum computer known as an oracle that implements some function: : {,} {,} The function takes n-bit binary values as input and produces either a 0 or a 1 as output for each such value.
In the COBOL programming language, a user-defined function is an entity that is defined by the user by specifying a FUNCTION-ID paragraph. A user-defined function must return a value by specifying the RETURNING phrase of the procedure division header and they are invoked using the function-identifier syntax.
an oracle tape, which is a semi-infinite tape separate from the work tape. The alphabet for the oracle tape may be different from the alphabet for the work tape. an oracle head which, like the read/write head, can move left or right along the oracle tape reading and writing symbols; two special states: the ASK state and the RESPONSE state.
A rusting Sun Microsystems van as seen at the Oracle-acquired Santa Clara, California campus in 2016. Several notable engineers resigned following the acquisition, including James Gosling, the creator of Java (resigned April 2010); Tim Bray, the creator of XML (resigned February 2010); Kohsuke Kawaguchi, lead developer of Hudson (resigned April 2010); and Bryan Cantrill, the co-creator of ...
The matrix sign function is a generalization of the complex signum function = {() >, <, to the matrix valued analogue ().Although the sign function is not analytic, the matrix function is well defined for all matrices that have no eigenvalue on the imaginary axis, see for example the Jordan-form-based definition (where the derivatives are all zero).
Some languages, such as PHP, provide functions that round a value to a specified number of decimal digits (e.g., from 4321.5678 to 4321.57 or 4300). In addition, many languages provide a printf or similar string formatting function, which allows one to convert a fractional number to a string, rounded to a user-specified number of decimal places ...
The sign of a complex number is the exponential of the product of its argument with the imaginary unit. represents in some sense its complex argument. This is to be compared to the sign of real numbers, except with = For the definition of a complex sign-function. see § Complex sign function below.
