# Roc Linear Algebra

Linear algebra library for small vectors and matrices in Roc.

## Example

Import a matrix and vector type.

```roc

import linalg.Matrix4x4

import linalg.Vector4

```

Vectors are just tuples.

```roc

vecA = (1, 2, 3, 4)

Stdout.line! "Vector a is $(Vector4.display vecA)."

vecB = (5, 6, 7, 8)

Stdout.line! "Vector b is $(Vector4.display vecB)."

```

```text

Vector a is [1, 2, 3, 4].

Vector b is [5, 6, 7, 8].

```

Vectors have various vector-y functions that work how you'd expect.

```roc

vecC = Vector4.add vecA vecB

Stdout.line! "The sum of a and b is $(Vector4.display vecC)."

aDotB = Vector4.dot vecA vecB

Stdout.line! "The dot product of a and b is $(Num.toStr aDotB)."

```

```text

The sum of a and b is [6, 8, 10, 12].

The dot product of a and b is 70.

```

Matrices are opaque types.

```roc

mat = Matrix4x4.fromDiagonal vecC

```

Matrices also have matrix-y functions.

```roc

det = Matrix4x4.determinant mat

Stdout.line! "The determinant of the matrix is $(Num.toStr det)."

```

```text

The determinant of the matrix is 5760.

```
