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

Description

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

Usage

Update_H_Tang(Y, W_itr, H_itr, eta)

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
eta	$\lambda$ is the parameter for ensuring column sums of H are 1s

Value

'Update_H_Tang' returns the udpated H matrix after iteration
