Randomorg_Matlab

A toolbox that fetches true random numbers from Random.org!

Motivation

Installation

After cloning or extracting the downloaded zip from within the Matlab GUI

Navigate to the extracted folder and run the "Randomorg_API.mltbx" file.

Following are the available functions :

generateIntegers(n, min, max, replacement)

This method generates true random integers within a user-defined range.

• n How many random integers you need. Must be within the [1,1e4] range.
• min The lower boundary for the range from which the random numbers will be picked. Must be within the [-1e9,1e9] range.
• max The upper boundary for the range from which the random numbers will be picked. Must be within the [-1e9,1e9] range.
• replacement Specifies whether the random numbers should be picked with replacement. The default (true) will cause the numbers to be picked with replacement, i.e., the resulting numbers may contain duplicate values. If you want the numbers picked to be unique set this value to false.

generateIntegerSequences(n, length, min, max, replacement)

This method generates uniform or multiform sequences of true random integers within user-defined ranges.

• n An integer specifying the number of sequences requested. Must be within the [1,1000] range.
• length This parameter specifies the lengths of the sequences requested.
  1) For uniform sequences, length must be an integer in the [1,10000] range.
  2) For multiform sequences, length can be an array with n integers, each specifying the length of the sequence.
  3) In this case, each value in length must be within the [1,10000] range and the total sum of all the lengths must be in the [1,10000] range.
• min This parameter specifies the lower boundaries of the sequences requested.
  1) For uniform sequences, min must be an integer in the [-1000000000,1000000000] range.
  2) For multiform sequences, min can be an array with n integers, each specifying the lower boundary of the sequence identified by its index.
  3) In this case, each value in min must be within the [-1000000000,1000000000] range.
• max This parameter specifies the upper boundaries of the sequences requested.
  1) For uniform sequences, max must be an integer in the [-1000000000,1000000000] range. 2) For multiform sequences, max can be an array with n integers, each specifying the upper boundary of the sequence identified by its index. 3) In this case, each value in max must be within the [-1000000000,1000000000] range.
• replacement Specifies whether the random numbers should be picked with replacement. The default (true) will cause the numbers to be picked with replacement,
  i.e., the resulting numbers may contain duplicate values. If you want the numbers picked to be unique set this value to false.

generateDecimalFractions(n, decimalPlaces, replacement)

This method generates true random decimal fractions from a uniform distribution across the [0,1] interval with a user-defined number of decimal places.

• n How many random decimal fractions you need. Must be within the [1,10000] range.
• decimalPlaces The number of decimal places to use. Must be within the [1,14] range.

generateGaussians(n, mean, standardDeviation, significantDigits)

This method generates true random numbers from a Gaussian distribution (also known as a normal distribution).

(The form uses a Box-Muller Transform to generate the Gaussian distribution from uniformly distributed numbers)

• n How many random numbers you need. Must be within the [1,10000] range.
• mean The distribution's mean. Must be within the [-1000000,1000000] range.
• standardDeviation The distribution's standard deviation. Must be within the [-1000000,1000000] range.
• significantDigits The number of significant digits to use. Must be within the [2,14] range.

generateStrings(n, length, characters, replacement)

This method generates true random strings.

• n How many random strings you need. Must be within the [1,10000] range.
• length The length of each string. Must be within the [1,32] range. All strings will be of the same length.
• characters A string that contains the set of characters that are allowed to occur in the random strings. The maximum number of characters is 128.
• replacement Specifies whether the random numbers should be picked with replacement. The default (true) will cause the numbers to be picked with replacement,
  i.e., the resulting numbers may contain duplicate values. If you want the numbers picked to be unique set this value to false.

generateUUIDs(n)

This method generates version 4 true random Universally Unique IDentifiers (UUIDs) in accordance with section 4.4 of RFC 4122.

• n How many random UUIDs you need. Must be within the [1,1000] range.

generateBlobs(n, size, format)

This method generates Binary Large OBjects (BLOBs) containing true random data.

• n How many random blobs you need. Must be within the [1,100] range.
• size The size of each blob, measured in bits. Must be within the [1,1048576] range and must be divisible by 8. The total size of all blobs requested must not exceed 1,048,576 bits (128 KiB).
• format Specifies the format in which the blobs will be returned. Values allowed are base64 and hex.
