Function Documentation

◆ sqrt()

template<typename Number , std::size_t width>
::VectorizedArray<Number, width> std::sqrt ( const ::VectorizedArray< Number, width > &  x)

Compute the square root of a vectorized data field. The result is returned as vectorized array in the form {sqrt(x[0]), sqrt(x[1]), ..., sqrt(x[size()-1])}.

Definition at line 5406 of file vectorization.h.

◆ abs()

template<typename Number , std::size_t width>
::VectorizedArray<Number, width> std::abs ( const ::VectorizedArray< Number, width > &  x)

Compute the absolute value (modulus) of a vectorized data field. The result is returned as vectorized array in the form {abs(x[0]), abs(x[1]), ..., abs(x[size()-1])}.

Definition at line 5444 of file vectorization.h.

◆ max()

template<typename Number , std::size_t width>
::VectorizedArray<Number, width> std::max ( const ::VectorizedArray< Number, width > &  x,
const ::VectorizedArray< Number, width > &  y 
)

Compute the componentwise maximum of two vectorized data fields. The result is returned as vectorized array in the form {max(x[0],y[0]), max(x[1],y[1]), ...}.

Definition at line 5460 of file vectorization.h.

◆ min()

template<typename Number , std::size_t width>
::VectorizedArray<Number, width> std::min ( const ::VectorizedArray< Number, width > &  x,

)

Compute the componentwise minimum of two vectorized data fields. The result is returned as vectorized array in the form {min(x[0],y[0]), min(x[1],y[1]), ...}.

Definition at line 5477 of file vectorization.h.

◆ pow()

template<typename Number , size_t width>
::VectorizedArray<Number, width> std::pow ( const ::VectorizedArray< Number, width > &  x,
const Number  p 
)

Raises the given number x to the power p for a vectorized data field. The result is returned as vectorized array in the form {pow(x[0],p), pow(x[1],p), ..., pow(x[size()-1],p)}.

Definition at line 5422 of file vectorization.h.

◆ sin()

template<typename Number , size_t width>
