Getting Started

This section will give an short overview about vectors and matrices.

Creation

The NumArray can present a scalar, a vector, a matrix or even a multidimensional array.

Example: Matrix

$matrix = new NumArray(
    [
        [   5, 5/6, -2.8],
        [0.65,  -3,  7/2]
    ]
);

Example: Vector

$vector = new NumArray(
    [78, 3.85, 1/45, 0]
);

Example: Scalar

$scalar = new NumArray(6);

Arithmetic

Here are some basic operations for matrices and vectors

Example: Addition

$sum = $matrix1->add($matrix2);

Example: Subtraction

$sub = $vector1->sub($vector2);

Example: Multiplication

$prod = $matrix->dot($vector);
