Kernel (matrix) - Left Null Space

The left null space of a matrix A consists of all vectors x such that xTA = 0T, where T denotes the transpose of a column vector. The left null space of A is the same as the null space of AT. The left null space of A is the orthogonal complement to the column space of A, and is the cokernel of the associated linear transformation. The null space, the row space, the column space, and the left null space of A are the four fundamental subspaces associated to the matrix A.

Famous quotes containing the words left, null and/or space:

    “And so they have left us feeling tired and old.
    They never cared for school anyway.
    And they have left us with the things pinned on the bulletin board.
    And the night, the endless, muggy night that is invading our school.”
    —John Ashbery (b. 1927)

    “A strong person makes the law and custom null before his own will.”
    —Ralph Waldo Emerson (1803–1882)

    “The true gardener then brushes over the ground with slow and gentle hand, to liberate a space for breath round some favourite; but he is not thinking about destruction except incidentally. It is only the amateur like myself who becomes obsessed and rejoices with a sadistic pleasure in weeds that are big and bad enough to pull, and at last, almost forgetting the flowers altogether, turns into a Reformer.”
    —Freya Stark (1893–1993)
