The left null space, or cokernel, of a matrix A consists of all column vectors x such that x T A = 0 T, where T denotes the transpose of a matrix. The left null space of A is the same as the kernel of A T. The left null space of A is the orthogonal complement to the column space of A, and is dual to the cokernel of the
The left null space of A is the set of all vectors x such that x T A = 0 T. It is the same as the null space of the transpose of A. The product of the matrix A T and the vector x can be written in terms of the dot product of vectors:
The vector space of matrices over is denoted by . For A ∈ K m × n {\displaystyle A\in \mathbb {K} ^{m\times n}} , the transpose is denoted A T {\displaystyle A^{\mathsf {T}}} and the Hermitian transpose (also called conjugate transpose ) is denoted A ∗ {\displaystyle A^{*}} .

In linear algebra, the transpose of a matrix is an operator which flips a matrix over its diagonal; that is, it switches the row and column indices of the matrix A by producing another matrix, often denoted by A T (among other notations). [1] The transpose of a matrix was introduced in 1858 by the British mathematician Arthur Cayley. [2]

Mathematical applications of the SVD include computing the pseudoinverse, matrix approximation, and determining the rank, range, and null space of a matrix. The SVD is also extremely useful in all areas of science, engineering , and statistics , such as signal processing , least squares fitting of data, and process control .
