Detailed Description

template<class SCALARTYPE, unsigned int ALIGNMENT = 1>
class viennacl::vandermonde_matrix< SCALARTYPE, ALIGNMENT >

A Vandermonde matrix class.

Template Parameters

NumericT	The underlying scalar type (either float or double)
AlignmentV	The internal memory size is given by (size()/AlignmentV + 1) * AlignmentV. AlignmentV must be a power of two. Best values or usually 4, 8 or 16, higher values are usually a waste of memory.

Examples:: structured-matrices.cpp.
