The Null space of a matrix is the set of vectors which post multiplying column wise or pre multiplying row wise produce the  zero vector, and are not the trivial zero vector themselves. The set of all Vectors basis coefficients * lambda = λ*v = the set of all vectorsContinue Reading

Column Space – The vector space that is spanned by all the C(A) columns in the matrix (A), can also be by row notation written as R(Transpose(A)) If a vector is contained in the column space of a certain matrix, then that vector is a column vector and the coefficients/weights neededContinue Reading
