In array languages, operations are generalized to apply to both scalars and arrays. Thus, a+b expresses the sum of two scalars if a and b are scalars, or the sum of two arrays if they are arrays. An array language simplifies programming but possibly at a cost known as the abstraction penalty.
BLOPEX (Block Locally Optimal Preconditioned Eigenvalue Xolvers) is an open-source library for the scalable solution of eigenvalue problems. FFTW (Fastest Fourier Transform in the West) is a software library for computing Fourier and related transforms. GNU Scientific Library, a popular, free numerical analysis library implemented in C.
An array data structure can be mathematically modeled as an abstract data structure (an abstract array) with two operations get(A, I): the data stored in the element of the array A whose indices are the integer tuple I. set(A, I, V): the array that results by setting the value of that element to V. These operations are required to satisfy the ...
The subset sum problem (SSP) is a decision problem in computer science. In its most general formulation, there is a multiset S {\displaystyle S} of integers and a target-sum T {\displaystyle T} , and the question is to decide whether any subset of the integers sum to precisely T {\displaystyle T} .

He led the design and implementation of numerous Java platform features, including the Java Collections Framework, the java.math package, and the assert mechanism. [1] He is the author of the programming guide Effective Java (2001), which won the 2001 Jolt Award , [ 2 ] and is a co-author of two other Java books, Java Puzzlers (2005) and Java ...
Dartmouth BASIC is the original version of the BASIC programming language.It was designed by two professors at Dartmouth College, John G. Kemeny and Thomas E. Kurtz.With the underlying Dartmouth Time-Sharing System (DTSS), it offered an interactive programming environment to all undergraduates as well as the larger university community.
Some properties of this problem are: If the array contains all non-negative numbers, then the problem is trivial; a maximum subarray is the entire array. If the array contains all non-positive numbers, then a solution is any subarray of size 1 containing the maximal value of the array (or the empty subarray, if it is permitted).
Thus a one-dimensional array is a list of data, a two-dimensional array is a rectangle of data, [12] a three-dimensional array a block of data, etc. This should not be confused with the dimension of the set of all matrices with a given domain, that is, the number of elements in the array.
