Performs the LU factorization of a matrix.
A real matrix.
This input accepts a 2D array of double-precision, floating point numbers or 2D array of complex double-precision, floating point numbers.
Default: Empty array
Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.
Default: No error
A lower triangular matrix with ones on the diagonal.
An upper triangular matrix.
A permutation matrix.
Error information. The node produces this output according to standard error behavior.
This node factors an m × n matrix A into the following types of matrices so that PA = LU:
For a singular matrix, this node completes the factorization and returns a warning, and there is at least one zero at the diagonal of U.
The following equation illustrates one useful property of LU factorization when A is a square matrix:
where det(A) is the determinant of A.
