  2. APL syntax and symbols - Wikipedia

    Some functions can be followed by an axis indicator in (square) brackets, i.e., this appears between a function and an array and should not be confused with array subscripts written after an array. For example, given the ⌽ (reversal) function and a two-dimensional array, the function by default operates along the last axis but this can be ...

    en.wikipedia.org/wiki/Generating_function

    The ordinary generating function of a two-dimensional array a m,n (where n and m are natural numbers) is: (,;,) =, =,. For instance, since (1 + x ) n is the ordinary generating function for binomial coefficients for a fixed n , one may ask for a bivariate generating function that generates the binomial coefficients ( n

  4. Generator (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Generator_(computer...

    In computer science, a generator is a routine that can be used to control the iteration behaviour of a loop. All generators are also iterators. [1] A generator is very similar to a function that returns an array, in that a generator has parameters, can be called, and generates a sequence of values.

  5. Menger sponge - Wikipedia

    Begin with a cube. Divide every face of the cube into nine squares in a similar manner to a Rubik's Cube. This sub-divides the cube into 27 smaller cubes. Remove the smaller cube in the middle of each face, and remove the smaller cube in the center of the larger cube, leaving 20 smaller cubes. This is a level-1 Menger sponge (resembling a void ...

  6. Cubic equation - Wikipedia

    Also, the use of principal cube root may give a wrong result if the coefficients are non-real complex numbers. Moreover, if the coefficients belong to another field, the principal cube root is not defined in general. The second way for making Cardano's formula always correct, is to remark that the product of the two cube roots must be –p / 3.

  7. Linear congruential generator - Wikipedia

    en.wikipedia.org/wiki/Linear_congruential_generator

    The second row is the same generator with a seed of 3, which produces a cycle of length 2. Using a = 4 and c = 1 (bottom row) gives a cycle length of 9 with any seed in [0, 8]. A linear congruential generator (LCG) is an algorithm that yields a sequence of pseudo-randomized numbers calculated with a discontinuous piecewise linear equation.

    The real part of the invariant g 3 as a function of the square of the nome q on the unit disk. The imaginary part of the invariant g 3 as a function of the square of the nome q on the unit disk. The coefficients of the above differential equation g 2 and g 3 are known as the invariants.

  9. Bilinear map - Wikipedia

    en.wikipedia.org/wiki/Bilinear_map

    A bilinear map is a function: such that for all , the map (,) is a linear map from to , and for all , the map (,) is a linear map from to . In other words, when we hold the first entry of the bilinear map fixed while letting the second entry vary, the result is a linear operator, and similarly for when we hold the second entry fixed.
