Get Number of Nonzeros VI

Owning Palette: Matrix VIs

Requires: Multicore Analysis and Sparse Matrix Toolkit

Returns the number of nonzeros and the maximum number of nonzeros in a sparse matrix.

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

Details  Example

Get Sparse Matrix NNZ (DBL)

	Sparse Matrix specifies the input sparse matrix.
	error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
	number of nonzeros returns the number of nonzeros in Sparse Matrix.
	max number of nonzeros returns the maximum number of nonzeros in Sparse Matrix.
	error out contains error information. This output provides standard error out functionality.

Get Sparse Matrix NNZ (SGL)

	Sparse Matrix specifies the input sparse matrix.
	error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
	number of nonzeros returns the number of nonzeros in Sparse Matrix.
	max number of nonzeros returns the maximum number of nonzeros in Sparse Matrix.
	error out contains error information. This output provides standard error out functionality.

Get Sparse Matrix NNZ (CDB)

	Sparse Matrix specifies the input sparse matrix.
	error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
	number of nonzeros returns the number of nonzeros in Sparse Matrix.
	max number of nonzeros returns the maximum number of nonzeros in Sparse Matrix.
	error out contains error information. This output provides standard error out functionality.

Get Sparse Matrix NNZ (CSG)

	Sparse Matrix specifies the input sparse matrix.
	error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
	number of nonzeros returns the number of nonzeros in Sparse Matrix.
	max number of nonzeros returns the maximum number of nonzeros in Sparse Matrix.
