Apply UOT coupling as a barycentric map (dense, matrix signal)

Matrix version for time series or multi-contrast signals.

Usage

uot_apply_map_dense_mat_cpp(
  cost,
  alpha,
  beta,
  fbar,
  gbar,
  epsilon,
  signal,
  delta = 1e-08
)

Arguments

cost

Dense cost matrix (n x m).

alpha

Source masses (length n).

beta

Target masses (length m).

fbar

Translation-invariant source potential (length n).

gbar

Translation-invariant target potential (length m).

epsilon

Entropic regularization parameter (> 0).

signal

Source signal matrix (T x n).

delta

Stabilizer added to the denominator.

Value

A numeric matrix (T x m) in template space.
