update_cols: subspace update based on projection of sample in question

In kcygan/dryclean: rPCA based method to de-noise genomic coverage data

Description

Internal function that updates basis of low rank subspace after projecting sample in question by warm restart

Usage

update_cols(U, A, B, lambda1)

Arguments

U	(m markers x n samples) numeric matrix. The basis of low rank subspace. The dimensions are same as burnin matrix
A,	B m x n numeric matrices. Matrices to update subspace basis
lambda1	integer. Tuning parameter (default = 1/(sqrt(no. of markers in input vector))

Value

U (m markers x n samples) numeric matrix. updated basis U of subspace
