Description
1-dimensional meshes. Used by Interpolation.
- class Indexable a => Mesh a where
- meshLowerBound :: a -> Double
- meshUpperBound :: a -> Double

- uniformMesh :: (Double, Double) -> Int -> UniformMesh
- uniformMeshN :: Double -> Double -> Int -> UniformMesh
Meshes
class Indexable a => Mesh a whereSource
Class for 1-dimensional meshes. Mesh is ordered set of points. Each instance must guarantee that every next point is greater that previous and there is at least 2 points in mesh.
Every mesh is instance of Indexable and indexing should get n'th
mesh node.
Methods
meshLowerBound :: a -> DoubleSource
Low bound of mesh
meshUpperBound :: a -> DoubleSource
Upper bound of mesh
meshFindIndex :: a -> Double -> IntSource
Find such index for value that
mesh ! i <= x && mesh ! i+1 > x
Will return invalid index if value is out of range.
Instances
Uniform mesh
data UniformMesh Source
Uniform mesh
uniformMeshStep :: UniformMesh -> DoubleSource
Distance between points
