Class generator_expj¶

`class` generator_expj<T, VecWidth> base ¶

template <typename T, size_t VecWidth = internal::generator_width<T>(2)>
struct generator_expj : public generator<T, VecWidth, generator_expj<T, VecWidth>> { … }

Generator that produces a complex exponential \(x_i = e^{ j ( start + i \cdot step ) }\) .

Template parameters
T	Complex value type.
VecWidth	Native vector width.

`typedef` ST ¶

using ST = deep_subtype<T>

Fully qualified name: kfr::generator_expj<T, VecWidth>::ST

Declared at base/generators.hpp:250

`constructor` generator_expj<T, VecWidth>(ST, ST) ¶

generator_expj(ST start_, ST step_)

Constructs a complex exponential generator.

Parameters
start_	Phase of the first value to produce.
step_	Phase increment between successive values.

Fully qualified name: kfr::generator_expj<T, VecWidth>::generator_expj<T, VecWidth>(ST, ST)

Declared at base/generators.hpp:258

`function` sync(T) ¶

Reinitializes the generator so the next vector starts at phase start.

Parameters
start	Starting phase (complex value).

Fully qualified name: kfr::generator_expj<T, VecWidth>::sync(T)

Declared at base/generators.hpp:268

`function` next() ¶

Advances the complex rotation by one native vector width using the recurrence relation.

Fully qualified name: kfr::generator_expj<T, VecWidth>::next()

Declared at base/generators.hpp:274

`variable` step ¶

ST step

Fully qualified name: kfr::generator_expj<T, VecWidth>::step

Declared at base/generators.hpp:281

`variable` alpha ¶

ST alpha

Fully qualified name: kfr::generator_expj<T, VecWidth>::alpha

Declared at base/generators.hpp:282

`variable` beta ¶

ST beta

Fully qualified name: kfr::generator_expj<T, VecWidth>::beta

Declared at base/generators.hpp:283

`function` init_cossin(ST, ST) ¶

Initializes a vector of complex exponentials with angular frequency w and starting phase phase.

Parameters
w	Angular frequency increment per sample.
phase	Starting phase.

Returns
	Vector of complex exponentials.

Fully qualified name: kfr::generator_expj<T, VecWidth>::init_cossin(ST, ST)
