Define Documentation

#define GET_XFLOP_MatPowMult (  args   )

Value: (2.0 * ((const oski_traceargs_MatPowMult_t *)(args))->num_vecs \ * ((const oski_traceargs_MatPowMult_t *)(args))->power) Compute the "flop factor.".

Function Documentation

int oski_CheckArgsMatPowMult (  const oski_matrix_t  A_tunable, oski_matop_t  opA, int  power, oski_value_t  alpha, const oski_vecview_t  x_view, oski_value_t  beta, const oski_vecview_t  y_view, const oski_vecview_t  T_view, const char *  caller )

Check arguments passed to oski_MatPowMult(). Returns: 0 if all arguments are OK, or an error code (plus a call to the error handler) otherwise. Todo: Need more verbose error messages in the event that the vectors have improper dimensions.
