svd_like: Create a SVD-like low rank matrix factorization object

In LRMF3: Low Rank Matrix Factorization S3 Objects

Description

A low rank matrix factorization of a matrix X is parameterized by X ~= u %*% diag(d) %*% t(v). The object is "svd-like" because the middle matrix in the decomposition must be strictly diagonal.

Usage

svd_like(u, d, v, subclasses = NULL, ...)

Arguments

u	A matrix "left singular-ish" vectors.
d	A vector of "singular-ish" values.
v	A matrix of "right singular-ish" vectors.
subclasses	A character vector of subclasses. Optional, defaults to NULL.
...	Optional additional items to pass to the constructor.

Examples

s <- svd(as.matrix(trees))

# using the constructor directly
svd_like(s$u, s$d, s$v)

# coercing svd-like lists
as_svd_like(s)
