# Update_H_Tang: Update of H matrix in iteration 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

 1 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

## Examples

 1 This function is not supposed to be run independently
