hemv - Hermitian Matrix-Vector Product VI

Owning Palette: Basic Linear Algebra Subroutines VIs

Requires: Multicore Analysis and Sparse Matrix Toolkit

Calculates the product of a Hermitian matrix and a vector.

Wire data to the A, x, and y inputs to determine the polymorphic instance to use.

Details  

zhemv - Hermitian Matrix-Vector Product (CDB)

	A specifies a Hermitian matrix. This VI multiplies the first N rows and N columns of the triangular component of A that you select for matrix A type by x, where N is the number of elements in x. A must have at least N rows and N columns.
	x specifies a vector with N elements.
	y specifies a vector. y must have at least N elements. The default is an N-element vector with all elements equal to 0.
	matrix A type specifies whether this VI uses the upper or lower triangular matrix component of A to calculate the product. 2 Lower Triangular—Specifies that this VI uses the lower triangular matrix component of A. 3 Upper Triangular (default)—Specifies that this VI uses the upper triangular matrix component of A.
	error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
	alpha specifies a scalar that scales A*x. The default is 1.
	beta specifies a scalar that scales y. The default is 1.
	zhemv returns a vector of the same size as y. For the first N elements, this VI returns the results of alpha*A*x + beta*y. For any remaining elements, this VI returns the value of the element in y with the same index.
	error out contains error information. This output provides standard error out functionality.

	alpha specifies a scalar that scales A*x. The default is 1.
	beta specifies a scalar that scales y. The default is 1.
	chemv returns a vector of the same size as y. For the first N elements, this VI returns the results of alpha*A*x + beta*y. For any remaining elements, this VI returns the value of the element in y with the same index.
