trmv - Triangle Matrix-Vector Product VI

Owning Palette: Basic Linear Algebra Subroutines VIs

Requires: Full Development System

Calculates the product of a triangular matrix and a vector.

The data types you wire to the A and x inputs determine the polymorphic instance to use.

dtrmv - Triangle Matrix-Vector Product (DBL)

	operation A specifies the operation the VI performs on matrix A, resulting in matrix op(A). 0 Direct (default) 1 Conjugated & Transposed 2 Transposed
	A is a real triangular matrix. The VI multiplies the first N rows and the first N columns of op(A) by x, where N equals the number of elements in x. The number of rows and columns in op(A) must be greater than or equal to N.
	x is an N–element real vector.
	matrix A type specifies whether A is an upper or lower triangular matrix. 2 Lower Triangular—A is a lower triangular matrix. 3 Upper Triangular (default)—A is an upper triangular matrix.
	diagonal specifies the value of the diagonal elements of A. 0 Non-unit (default)—The VI uses the original diagonal elements of A. 1 Unit—The VI uses a value of 1 for all diagonal elements of A.
	dtrmv is a real vector of the same size as x that returns the result of op(A)*x.
	error returns any error or warning from the VI. You can wire error to the Error Cluster From Error Code VI to convert the error code or warning into an error cluster.

ztrmv - Triangle Matrix-Vector Product (CDB)

	operation A specifies the operation the VI performs on matrix A, resulting in matrix op(A). 0 Direct (default) 1 Conjugated & Transposed 2 Transposed
	A is a complex triangular matrix. The VI multiplies the first N rows and the first N columns of op(A) by x, where N equals the number of elements in x. The number of rows and columns in op(A) must be greater than or equal to N.
	x is an N–element complex vector.
	matrix A type specifies whether A is an upper or lower triangular matrix. 2 Lower Triangular—A is a lower triangular matrix. 3 Upper Triangular (default)—A is an upper triangular matrix.
	diagonal specifies the value of the diagonal elements of A. 0 Non-unit (default)—The VI uses the original diagonal elements of A. 1 Unit—The VI uses a value of 1 for all diagonal elements of A.
	ztrmv is a complex vector of the same size as x that returns the result of op(A)*x.
	error returns any error or warning from the VI. You can wire error to the Error Cluster From Error Code VI to convert the error code or warning into an error cluster.
