/**
|
|
* Return a random number larger or equal to `min` and smaller than `max`
|
|
* using a uniform distribution.
|
|
*
|
|
* Syntax:
|
|
*
|
|
* math.random() // generate a random number between 0 and 1
|
|
* math.random(max) // generate a random number between 0 and max
|
|
* math.random(min, max) // generate a random number between min and max
|
|
* math.random(size) // generate a matrix with random numbers between 0 and 1
|
|
* math.random(size, max) // generate a matrix with random numbers between 0 and max
|
|
* math.random(size, min, max) // generate a matrix with random numbers between min and max
|
|
*
|
|
* Examples:
|
|
*
|
|
* math.random(); // returns a random number between 0 and 1
|
|
* math.random(100); // returns a random number between 0 and 100
|
|
* math.random(30, 40); // returns a random number between 30 and 40
|
|
* math.random([2, 3]); // returns a 2x3 matrix with random numbers between 0 and 1
|

|
|
* @param {Array | Matrix} [size] If provided, an array or matrix with given
|
|
* size and filled with random values is returned
|
|
* @param {Number} [min] Minimum boundary for the random value, included
|
|
* @param {Number} [max] Maximum boundary for the random value, excluded
|
|
* @return {Number | Array | Matrix} A random number
