LU Decomposition VI

Owning Palette: Linear Algebra VIs

Requires: Multicore Analysis and Sparse Matrix Toolkit

Computes the LU decomposition of a matrix A so that PA = LU.

Wire data to the A input to determine the polymorphic instance to use or manually select the instance.

Details  

LU Decomposition (DBL)

	A specifies an m × n matrix with m rows and n columns.
	error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
	L returns the decomposed m × min(m, n) lower triangular matrix with ones as the diagonal elements.
	U returns the decomposed min(m, n) × n upper triangular matrix.
	P returns the decomposed m × m permutation matrix.
	error out contains error information. This output provides standard error out functionality.

LU Decomposition (SGL)

	A is an m × n matrix with m rows and n columns.
	error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
	L returns the decomposed m × min(m, n) lower triangular matrix with ones as the diagonal elements.
	U returns the decomposed min(m, n) × n upper triangular matrix.
	P returns the decomposed m × m permutation matrix.
	error out contains error information. This output provides standard error out functionality.

LU Decomposition (CDB)

	A specifies an m × n matrix with m rows and n columns.
	error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
	L returns the decomposed m × min(m, n) lower triangular matrix with ones as the diagonal elements.
	U returns the decomposed min(m, n) × n upper triangular matrix.
	P returns the decomposed m × m permutation matrix.
	error out contains error information. This output provides standard error out functionality.

LU Decomposition (CSG)

	A specifies an m × n matrix with m rows and n columns.
	error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
	L returns the decomposed m × min(m, n) lower triangular matrix with ones as the diagonal elements.
	U returns the decomposed min(m, n) × n upper triangular matrix.
	P returns the decomposed m × m permutation matrix.
	error out contains error information. This output provides standard error out functionality.
