Member Function Documentation

dot()

template<typename TValue >

static value_type jade::basic_blas< TValue >::dot ( const int  n, const value_type *  x, const int  incx, const value_type *  y, const int  incy  )

static

Computes a vector-vector dot product.

Returns

The result of the dot product of x and y, if n is positive. Otherwise, returns 0.

Parameters

n	The number of elements.
x	The X array.
incx	The X increment.
y	The Y array.
incy	The Y increment.

static

Computes a matrix-matrix product with general matrices.

Parameters

Order	The order.
TransA	Transpose A.
TransB	Transpose B.
