Some compiled languages such as Ada and Fortran, and some scripting languages such as IDL, MATLAB, and S-Lang, have native support for vectorized operations on arrays. For example, to perform an element by element sum of two arrays, a and b to produce a third c, it is only necessary to write c = a + b
NumPy (pronounced / ˈ n ʌ m p aɪ / NUM-py) is a library for the Python programming language, adding support for large, multi-dimensional arrays and matrices, along with a large collection of high-level mathematical functions to operate on these arrays. [3]
For example, the variable *read-base* controls in which base numbers are read by default. Variables to control the printer. Example: maximum length or maximum depth of expressions to print. Additional command syntax. Some REPLs have commands that follow not the s-expression syntax, but often work with Lisp data as arguments. Graphical REPLs.
Rather than representing a number as single value, some store numbers as a numerator/denominator pair and some can fully represent computable numbers, though only up to some storage limit. Fundamentally, Turing machines cannot represent all real numbers , as the cardinality of R {\displaystyle \mathbb {R} } exceeds the cardinality of Z ...
Binary search Visualization of the binary search algorithm where 7 is the target value Class Search algorithm Data structure Array Worst-case performance O (log n) Best-case performance O (1) Average performance O (log n) Worst-case space complexity O (1) Optimal Yes In computer science, binary search, also known as half-interval search, logarithmic search, or binary chop, is a search ...
For example, in the Pascal programming language, the declaration type MyTable = array [1.. 4, 1.. 2] of integer, defines a new array data type called MyTable. The declaration var A: MyTable then defines a variable A of that type, which is an aggregate of eight elements, each being an integer variable identified by two indices.
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.
B n is the number of partitions of a set with n elements. A000110: Euler zigzag numbers E n: 1, 1, 1, 2, 5, 16, 61, 272, 1385, 7936, ... E n is the number of linear extensions of the "zig-zag" poset. A000111: Lazy caterer's sequence: 1, 2, 4, 7, 11, 16, 22, 29, 37, 46, ... The maximal number of pieces formed when slicing a pancake with n cuts ...
