mcrals.fcnnls R Documentation
Fast combinatorial non-negative least squares
Description
Fast combinatorial non-negative least squares
Usage
mcrals.fcnnls(
D,
A,
tol = 10 * .Machine$double.eps * as.numeric(sqrt(crossprod(A[, 1]))) * nrow(A)
)
Arguments
D
a matrix
A
a matrix
tol
tolerance parameter for algorithm convergence
Details
Computes Fast combinatorial NNLS solution for B: D = AB' subject to B >= 0. Implements
the method described in [1].
