摘要
The present invention discloses a matrix inverse matrix solution module and a calculation method by an improved position displacement method. The matrix inverse matrix solution module of the present invention includes a boundary element acquisition unit, an internal element acquisition unit, a lower triangular matrix acquisition unit, an upper triangular matrix acquisition unit, and an inverse matrix acquisition unit. The boundary element acquisition unit is used to acquire the boundary element of the reduction coefficient matrix of the matrix for which the inverse matrix is to be found. The internal element acquisition unit is used to acquire the internal elements of the reduction coefficient matrix of the matrix whose inverse matrix is to be found. The lower triangular matrix acquisition unit is used to acquire the inverse matrix of the lower triangular matrix obtained by decomposition of the matrix to be obtained the inverse matrix. The upper triangular matrix acquisition unit is used to acquire the inverse matrix of the upper triangular matrix obtained by decomposition of the matrix whose inverse matrix is to be found. The inverse matrix obtaining unit is used to obtain the inverse matrix of the matrix to be obtained the inverse matrix.
