OM-Functions

The main functions in the OpenMadness JavaScript library are used for:

  1. Array creation and manipulation
  2. Arithmetic Operation
  3. Logic
  4. Statistics
  5. Transformations
  6. Utilities

Array Operations

These functions are available for creating or manipulating arrays:

1. mad.ones(shape)

This creates an array filled with ones:

ParameterTypeDescription
shapeArrayShape of the new array, e.g., [2, 3] or 2
ReturnsArrayA new array filled with ones

Example:

// Create a 3x1 array of ones
import { ones } from 'openmadness';

const onesColumn = ones([3, 1]);
// Result: [[1], [1], [1]]

2. mad.zeros(shape)

This creates an array filled with zeros:

ParameterTypeDescription
shapeArrayShape of the new array, e.g., [2, 3] or 2
ReturnsArrayA new array filled with zeros

Example:

// Create a 2x2 array of zeroes
import { zeros } from 'openmadness';

const zeroMatrix = zeros([2, 2]);
// Result: [[0, 0], [0, 0]]

3. mad.range(start, end, step)

This generates an array containing a sequence of numbers:

ParameterTypeDescription
startnumberStart of the range
endnumberEnd of the range
stepnumberStep increment. Default is 1
ReturnsArrayA new array with the number range

Example:

import { range } from 'openmadness';

const sequence = range(0, 10, 2);
// Result: [0, 2, 4, 6, 8]

4. mad.random(shape)

Generates an array of the given shape with random values between 0 and 1:

ParameterTypeDescription
shapeArrayShape of the new array
ReturnsArrayA new array filled with random values

Example:

import { random } from 'openmadness';

const randomArray = random([2, 2]);
// Example output: [[0.13, 0.85], [0.42, 0.67]]
