null.space {MSBVAR} | R Documentation |
Computes the null space of A for an arbitrary linear system of the form Ax = b.
null.space(x)
x |
m x n A matrix of a linear system Ax = b |
Computes the null space via singular value decomposition (SVD) of A by finding the columns of the SVD of A that correspond to the non-singular column vectors that span A.
Returns an m x q matrix that is the null space, where q is the rank of A.
