fiducia.cspline.dToyArr(chLen)

Construct matrix for converting from \(D_i\) to \(y_i\) vector.

Parameters

chLen (int) – Number of DANTE channels (equal to number of spline knots).

Returns

diToyi – Matrix for converting from \(D_i\) to \(y_i\) vector.

Return type

numpy.ndarray

Notes

The matrix is given by:

\[D_i = 3 \chi_1^{-1} \chi_3 y_i\]
