Update_W_Tang: Update of W matrix in iteration

In tdw1221/NITUMID: Non-negative Matrix Factorization-based Immune-TUmor MIcroenvironment Deconvolution

Description

'Update_W_Tang' conducts one simple iteration of W in the NMF process, however, it is designed as a sub-function for NMF procedure, do not run it indenpendently

Usage

Update_W_Tang(Y, W_itr, H_itr, beta_W, lam_W, A)

Arguments

Y	Y is the gene expression matrix that has #signature genes rows and #samples columns
W_itr	W matrix from previous step of iteration
H_itr	H matrix from previous step of iteration
beta_W	$\beta$ is the parameter controlling sparsity ridge penalty, see our paper for more information
lam_W	$\lambda$ is the parameter imposing A's structure into resulting W, see our paper for more info
A	The trichotomous guide matrix A

Value

'Update_W_Tang' returns the udpated W matrix after iteration

Examples

This function is not supposed to be run independently
