fromGriddedValues

Create an interpolating spline from values on a rectilinear grid.

---

Declaration

 self = fromGriddedValues(gridVectors,values,options)

Parameters

• gridVectors numeric vector in 1-D or cell array of grid vectors in higher dimensions
• values array of sampled values on the supplied grid
• options.S spline degree scalar or vector with one entry per dimension

Returns

• self InterpolatingSpline instance

Discussion

Use this factory for ordinary interpolation from gridded samples. It validates the gridded input, builds the knot sequence, normalizes the values, solves for the interpolation coefficients, and then delegates to the cheap constructor.
