Functions

int oski_ZeroVecView (oski_vecview_t x)
 Set all elements of a vector view $x$ to zero.
int oski_ScaleVecView (oski_vecview_t x, oski_value_t alpha)
 Computes $x \leftarrow \alpha\cdot x$.
int oski_ConjVecView (oski_vecview_t x)
 Computes the complex conjugate of a vector view, i.e., $x \leftarrow \bar{x}$.
int oski_AXPYVecView (const oski_vecview_t x, oski_value_t alpha, oski_vecview_t y)
 Computes $y \leftarrow y + \alpha\cdot x$.
int oski_RectScaledIdentityMult (oski_value_t alpha, const oski_vecview_t x, oski_vecview_t y)
 Computes $y \leftarrow y + \alpha I_{m\times n}\cdot x$, where $I_{m\times n}$ is an $m\times n$ matrix such that $I(k,k) = 1$ for all $1 \leq k \leq \min(m,n)$.
int oski_DenseMatMult (const oski_vecview_t A, oski_matop_t opA, oski_value_t alpha, const oski_vecview_t x, oski_value_t beta, const oski_vecview_t y)
 Computes $y \leftarrow \beta\cdot y + \alpha\cdot \mathrm{op}(A)\cdot x$, where $A, x, y$ are all dense matrices (multivector views).

Function Documentation

int oski_RectScaledIdentityMult (  oski_value_t  alpha,
const oski_vecview_t  x,
oski_vecview_t  y
) 
 

Computes $y \leftarrow y + \alpha I_{m\times n}\cdot x$, where $I_{m\times n}$ is an $m\times n$ matrix such that $I(k,k) = 1$ for all $1 \leq k \leq \min(m,n)$.

Precondition:
x and y must be valid views.

int oski_ScaleVecView (  oski_vecview_t  x,
oski_value_t  alpha
) 
 

Computes $x \leftarrow \alpha\cdot x$.

Parameters:
[in,out] x A valid vector view.
[in] alpha Scalar multiplier.

int oski_ZeroVecView (  oski_vecview_t  x  ) 
 

Set all elements of a vector view $x$ to zero.

Parameters:
[in] x Valid vector view.
Returns:
0 on success, or an error code on err.
