environmentaltools.graphics.smooth1D(y, lambda_)

Apply 1D smoothing to data using regularization matrix.

Implements smoothing through matrix operations with penalty terms based on first and second differences.

Parameters:

• y (array-like) – Input data to smooth (m x n array).

• lambda (float) – Smoothing parameter controlling penalty strength.

Returns:

Smoothed data with same shape as input.

Return type:

numpy.ndarray
