symm - Symmetric Matrix-Matrix Product VI

Owning Palette: Basic Linear Algebra Subroutines VIs

Requires: Full Development System

Calculates the product of a symmetric matrix and another matrix.

The data types you wire to the A, B, and C inputs determine the polymorphic instance to use.

dsymm - Symmetric Matrix-Matrix Product (DBL)

	side specifies the position of A in the calculation. 0 Right—The VI calculates the result of alpha*B*A. 1 Left (default)—The VI calculates the result of alpha*A*B.
	A is a real symmetric matrix that has at least K rows and K columns. The VI multiplies the first K rows and K columns of A by B. If you set side to Left, K equals the number of rows in B. If you set side to Right, K equals the number of columns in B.
	B is a real matrix.
	C is a real matrix. The dimensions of C must be greater than or equal to the dimensions of B. The default is a matrix the same size as matrix B with all elements equal to 0.
	matrix A type specifies whether the VI uses the upper or lower triangular component of A for the calculation. 2 Lower Triangular—The VI uses the lower triangular component of A for the calculation. 3 Upper Triangular (default)—The VI uses the upper triangular component of A for the calculation.
	alpha is a real scalar that scales A*B and B*A. The default is 1.
	beta is a real scalar that scales C. The default is 1.
	dsymm is a real matrix the same size as C. For the elements of the first K rows and K columns of triangular component you select, the VI returns the result of alpha*A*B + beta*C or alpha*B*A + beta*C, depending on the side you select. For any remaining elements, the VI returns the value of the element with the same index in C.
	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.

zsymm - Symmetric Matrix-Matrix Product (CDB)

	side specifies the position of A in the calculation. 0 Right—The VI calculates the result of alpha*B*A. 1 Left (default)—The VI calculates the result of alpha*A*B.
	A a complex symmetric matrix that has at least K rows and K columns. The VI multiplies the first K rows and K columns of A by B. If you set side to Left, K equals the number of rows in B. If you set side to Right, K equals the number of columns in B.
	B is a complex matrix.
	C is a complex matrix of dimensions greater than or equal to B. The default is a matrix the same size as matrix B with all elements equal to 0.
	matrix A type specifies whether the VI uses the upper or lower triangular component of A for the calculation. 2 Lower Triangular—The VI uses the lower triangular component of A for the calculation. 3 Upper Triangular (default)—The VI uses the upper triangular component of A for the calculation.
	alpha is a complex scalar that scales A*B or B*A. The default is 1.
	beta is a complex scalar that scales C. The default is 1.
	zsymm is a real matrix the same size as C. For the elements of the first K rows and K columns of the triangular component you select, the VI returns the result of alpha*A*B + beta*C or alpha*B*A + beta*C, depending on the side you select. For any remaining elements, the VI returns the value of the element with the same index in C.
	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.
