rand

Version:
    Last Modified: January 9, 2017

    Generates uniformly distributed pseudorandom numbers in the interval [0, 1].

    Syntax

    rand('seed',s)
    c = rand
    c = rand(a)
    c = rand(a, b)
    c = rand(a, b, ...)
    c = rand(v)
    c = rand(a, class)
    c = rand(a, b, class)
    c = rand(a, b, ..., class)
    c = rand(v, class)

    Inputs

    'seed'

    If used, the function generates the same series of pseudorandom numbers.

    a

    Number of rows in c. a is a non-negative integer. If a is zero, the function returns an empty array.

    b

    Number of columns in c. b is a non-negative integer. If b is zero, the function returns an empty array.

    ...

    Further parameters for specifying the number of elements in higher dimensions. You can replace one parameter for any dimension with an empty array, for example, reshapemx([1,2,3,4,5,6], 2, []). The array then is a placeholder for an unspecified size. MathScript uses the array size and the reshape size to calculate the unspecified size automatically.

    s

    Seed of the pseudorandom number generator used for the next call of the function.

    v

    Vector with number of rows, columns, and further dimensions. v must contain non-negative integer values.

    class

    Class of the returned array (optional).

    Name Description
    'double'

    double (default)

    'single'

    single

    Outputs

    c

    Array of uniformly distributed pseudorandom numbers in the interval [0, 1]. If you do not specify b, c returns a square matrix of length a.

    Syntax Details

    c = rand generates a single pseudorandom number. c = rand(a, b) is equivalent to c = rand([a, b]).

    A = [3, 4]
    C = rand(A)
