Helper function for updating precision matrix.

Description

Helper function for updating the precision matrices in the EMFA algorithm.

Usage

updatePrec(m, nc, omega, w, p, wNew, pNew, cNew, het, maxDiag)

Arguments

m	An integer, the order of the model.
nc	An integer, the number of traits or genotypes.
omega	A computed matrix for the current step in the algoritm.
w	A model matrix for the current step in the algorithm.
p	A model matrix for the current step in the algorithm.
wNew	A pointer to the updated model matrix for w.
pNew	A pointer to the updated model matrix for p.
cNew	A pointer to the updated matrix c.
het	Should an extra diagonal part be added in the model for the precision matrix.
maxDiag	A numerical value for the maximum value of sigma2.
