const ShGeneric< N, T2 > &  m2,
const ShGeneric< N, T3 > &  a
) 
 

Multiply and add.

This is an intrinsic to access the assembly instruction of the same name. Multiply-add is potentially cheaper than a separate multiply and add. Note: potentially.

template<int N, typename T1, typename T2>
ShGeneric< N, CT1T2 > SH::operator * (  const ShGeneric< N, T1 > &  left,
const ShGeneric< N, T2 > &  right
) 
 

Multiplication.

On tuples, this operator acts componentwise. If a scalar is multiplied by a tuple, the scalar is promoted by duplication to a tuple.

Definition at line 104 of file ShLibArithImpl.hpp.

template<int N, typename T1, typename T2>
ShGeneric< N, CT1T2 > SH::operator+ (  const ShGeneric< N, T1 > &  left,
const ShGeneric< N, T2 > &  right
) 
 

Addition.

On tuples, this operator acts componentwise.

Todo:
scalar promotion.

Definition at line 34 of file ShLibArithImpl.hpp.

template<int N, typename T1, typename T2>
ShGeneric< N, CT1T2 > SH::operator- (  const ShGeneric< N, T1 > &  left,
const ShGeneric< N, T2 > &  right
) 
 

Subtraction.

On tuples, this operator acts componentwise.

Todo:
scalar promotion.

Definition at line 69 of file ShLibArithImpl.hpp.

template<int N, typename T1, typename T2>
ShGeneric< N, CT1T2 > SH::operator/ (  const ShGeneric< N, T1 > &  left,
const ShGeneric< N, T2 > &  right
) 
 

Division.

On tuples, this operator acts componentwise. If a tuple is divided by a scalar (or vice versa), the scalar is promoted by duplication to a tuple.

Definition at line 139 of file ShLibArithImpl.hpp.

template<int N, typename T1, typename T2, typename T3>
ShGeneric< N, CT1T2 > SH::pow (  const ShGeneric< N, T1 > &  left,
const ShGeneric< N, T2 > &  right
) 
 

Power.

Raise a tuple to a power.

Todo:
scalar promotion.
