The Hadamard code is a linear code, and all linear codes can be generated by a generator matrix.This is a matrix such that () = holds for all {,}, where the message is viewed as a row vector and the vector-matrix product is understood in the vector space over the finite field.
When code generation occurs at runtime, as in just-in-time compilation (JIT), it is important that the entire process be efficient with respect to space and time. For example, when regular expressions are interpreted and used to generate code at runtime, a non-deterministic finite-state machine is often generated instead of a deterministic one, because usually the former can be created more ...

Improvisation in engineering is to solve a problem with the tools and materials immediately at hand. [17] Examples of such improvisation was the re-engineering of carbon dioxide scrubbers with the materials on hand during the Apollo 13 space mission, [ 18 ] or the use of a knife in place of a screwdriver to turn a screw.
The codewords of this cyclic code are all the polynomials that are divisible by this generator polynomial. Codewords are polynomials of degree ⩽ n − 1 {\displaystyle \leqslant n-1} . Suppose that the generator polynomial g ( x ) {\displaystyle g(x)} has degree r {\displaystyle r} .
Signetics continued the development of the 2650, introducing two new models in 1977. The 2650A was a reworked version of the original layout intended to improve yield, and thus reduce cost. Speed remained unchanged at 1.25 MHz for the base model and 2 MHz for the -1 versions.
The RM(0, m) code is the repetition code of length N =2 m and weight N = 2 m−0 = 2 m−r. By 1 (,) = and has weight 1 = 2 0 = 2 m−r. The article bar product (coding theory) gives a proof that the weight of the bar product of two codes C 1, C 2 is given by
CodeMonkey is an educational computer coding environment that allows beginners to learn computer programming concepts and languages. [2] [3] [4] CodeMonkey is intended for students ages 6–14.
