Zero order spline coefficients (n), corresponding to line intersects

Field type: float[]

sample points (n+1), sorted ascending

Field type: float[]

Determines the coefficients of the derivative of the given step function.

Returns: StepCoef

Coefficients of the fst derivative of the linear spline

Predicts the y value at point x. A straight line is fitted between the neighboring x values given.

X values that don't not lie within the range of the input x values, are predicted using the nearest interpolation line!

Returns: float -> float

Y value corresponding to the given x value.

Example

 
 // e.g. days since a certain event
 let xData = vector [|0.;1.;5.;4.;3.;|]
 // some measured feature
 let yData = vector [|1.;5.;4.;13.;17.|]
 
 // get slopes and intersects for interpolating straight lines
 let coefficients = 
     Interpolation.Step.interpolate xData yData 

 // get y value at 3.4
 coefficients.Predict 3.4

Calculates slope values at X=x with given step function coefficients.

x : 'a

x value of which the corresponding y value slope should be predicted

Returns: float

predicted slope of given step function at X=x

xValues : float[]

c0 : float[]

Returns: StepCoef
