Update V

Description

Function to update V using given Delta and U. The new V is set as X Y^T, where SVD of D^T U Delta = X Sigma Y^T.

Usage

updateV(mat_list, u, d)

Arguments

mat_list	A list containing numeric matrices
u	A list containing U matrices
d	A list containing delta matrices

Value

a list containing new U matrices

Examples

set.seed(1231)
mymat <- createRandomMatrices(n = 3, ncols = 3, nrows = 3)
sbf <- SBF(matrix_list = mymat, orthogonal = FALSE,
           transform_matrix = FALSE)
newU <- updateU(mymat, sbf$delta, sbf$v)
newDelta <- updateDelta(mymat, newU, sbf$v)
newV <- updateV(mymat, newU, newDelta)
