proj_hs {mig} | R Documentation |
Orthogonal projection matrix onto the half-space
Description
The orthogonal projection matrix P
has unit determinant and
transforms an n
by d
matrix by taking x * P
.
The components of the first column vector of the resulting matrix are strictly positive.
Usage
proj_hs(beta, inv = FALSE)
Arguments
beta |
vector defining the half-space |
inv |
logical; if |
Value
a d
by d
orthogonal projection matrix
