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.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
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.
