Matrix Constructor

Class Constructor

• new [Type]Matrix(r, c, arr: (number)[]) : Creates an r × c matrix using the provided array of numbers.
• new [Type]Matrix(m : [Type]Matrix) : Creates a copy of an existing [Type]Matrix.
• new [Type]Matrix(arr : (number)[][]) : Creates a matrix from a 2-dimensional array. The number of rows and columns is inferred from the array shape.

Example

const M1 = new I8Matrix(3, 3, [1, 2, 3, -4, -5, 6, 7, 8, 9])
const M2 = new I8Matrix(M1)
const M3 = new F32Matrix([
              [1.3, 1.2],
              [-3.7, 2.75]
            ])

Functional Constructors

• matrix_[type](r, c, arr: (number)[]) : Functional version of the constructor that creates an r × c matrix from a flat array.

• matrix_[type](m : [Type]Matrix) : Functional copy of an existing [Type]Matrix.

• matrix_[type](arr : (number)[]) : Functional constructor that creates a matrix from a 2-dimensional array.

Example

const M1 = matrix_i8(3, 3, [1, 2, 3, -4, -5, 6, 7, 8, 9])
const M2 = matrix_i8(M1)
const M3 = matrix_f32([
              [1.3, 1.2],
              [-3.7, 2.75]
            ])

Static Factory Methods

All TypedMatrix classes (F16Matrix, F32Matrix, F64Matrix, I8Matrix, etc.) provide the following static factory methods for convenient construction:

• [Type]Matrix.zeros(r, c) : Creates an r × c matrix filled with zeros.
• [Type]Matrix.ones(r, c) : Creates an r × c matrix filled with ones.
• [Type]Matrix.eye(n) : Creates an n × n identity matrix (ones on the diagonal, zeros elsewhere).
• [Type]Matrix.nums(r, c, num : number) : Creates an r × c matrix filled with the specified value num
• Matrix.random.int(min, max)
• Matrix.random.float(min, max)

Example

 const M1 = F64Matrix.zeros(2,7)
 const M2 = U32Matrix.ones(4,5)
 const M3 = I32Matrix.eye(4)
 const M4 = F32Matrix.nums(3, 3, -1.25)
 const M5 = I16Matrix.random.int(-7, 7)
 const M6 = F32Matrix.random.float(-7, 7)
