%description
Provide regularized maximum covariance analysis incorporating smoothness,
sparseness and orthogonality of couple patterns by using the alternating
direction method of multipliers algorithm. The method can be applied to
either regularly or irregularly spaced data, including 1D, 2D, and 3D
(Wang and Huang, 2017 <doi:10.1002/env.2481>).
