Sentence examples for point matrix from inspiring English sources

Fixed point matrix inversion was implemented using LU decomposition and triangular matrix inversion.

The global transfer matrix is obtained by applying boundary conditions of the tower and constructing the point matrix.

Once the matrix has been determined, the entire structure matrix is obtained by the product of the transfer matrix of the shell and the point matrix at the joint of the structure matrix.

Once the matrix has been determined, the entire structure matrix is obtained by the product of the transfer matrices of the shells and the point matrix at the joint, and the frequency equation is derived with terms of the elements of the structure matrix under the boundary conditions.
