update_C: Update sub-matrix C

In OSNMTF: Orthogonal Sparse Non-Negative Matrix Tri-Factorization

Description

Update sub-matrix C

Usage

update_C(W,update_R_list,lambda=0.2,rho=1.1)

Arguments

W	The matrix to be factorized
update_R_list	A list containing the updated results in this iteration after running the function update_R
lambda	A parameter to set the relative weight of the sparsity constraints
rho	A parameter used in the augmented lagrange multiplier method

Value

A list the same as update_R_list with the matrix C updated

Examples

W <- simu_data_generation()
init_list <- initialization(W,k=5,l=4)
update_L_list <- update_L(W,init_list)
update_B_list <- update_B(W,update_L_list)
update_R_list <- update_R(W,update_B_list)
update_C_list <- update_C(W,update_R_list,lambda=0.2,rho=1.1)
