Embodiment Construction
[0135] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0136] Explanation of terms:
[0137] 1) Givens orthogonal row transformation: Perform Givens orthogonal decomposition on a non-singular matrix, and use row transformation to decompose all rows row by row.
[0138] 2) Givens orthogonal incremental row transformation: When performing Givens orthogonal decomposition on a non-singular matrix, when the matrix changes locally, inherit the calculated results before the matrix change, continue to decompose by adding element rows, and finally get a fast matrix with correct results Orthogonal decomposition technique.
[0139] 3) Incremental row: the newly added element row constructed during Givens orthogonal incremental row transformation.
[0140] 4) Incremental matrix: a matrix formed by all newly added element rows constructed during the Givens orthogonal incremental row transformation process.
[0141] 5) Forw...
