Linear algebra library for small vectors and matrices in Roc.
Import a matrix and vector type.
import linalg.Matrix4x4
import linalg.Vector4Vectors are just tuples.
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)."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.
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)."The sum of a and b is [6, 8, 10, 12].
The dot product of a and b is 70.
Matrices are opaque types.
mat = Matrix4x4.fromDiagonal vecCMatrices also have matrix-y functions.
det = Matrix4x4.determinant mat
Stdout.line! "The determinant of the matrix is $(Num.toStr det)."The determinant of the matrix is 5760.
