Eigen_kernel | R Documentation |
Kernel (null-space) of a real or complex matrix.
Eigen_kernel(M, method = "COD")
M |
a matrix, real or complex |
method |
one of |
A basis of the kernel of M
. With method = "COD"
, the
basis is orthonormal, while it is not with method = "LU"
.
set.seed(666) M <- matrix(rgamma(30L, 12, 1), 10L, 3L) M <- cbind(M, M[,1]+M[,2], M[,2]+2*M[,3]) # basis of the kernel of `M`: Eigen_kernel(M, method = "LU") # orthonormal basis of the kernel of `M`: Eigen_kernel(M, method = "COD")
