Detailed Description

Workspace for solving polynomials.

This has to represent complex roots.

Definition at line 43 of file poly.hpp.

Constructor & Destructor Documentation

◆ complex_workspace() [1/5]

gsl::poly::complex_workspace::complex_workspace ( )

inline

The default constructor is only really useful for assigning to.

Definition at line 48 of file poly.hpp.

References ccgsl_pointer, and count.

Referenced by operator=().

◆ complex_workspace() [2/5]

gsl::poly::complex_workspace::complex_workspace ( size_t const n )

inlineexplicit

The default constructor creates a new complex_workspace with n elements.

This workspace is suitable for solving a polynomial with n components.

Parameters

n	The number of elements in the complex_workspace

Definition at line 59 of file poly.hpp.

References ccgsl_pointer, count, and gsl::rstat::n().

◆ complex_workspace() [3/5]

gsl::poly::complex_workspace::complex_workspace ( gsl_poly_complex_workspace * v )

inlineexplicit

Could construct from a gsl_poly_complex_workspace.

This is not usually a good idea. In this case you should not use gsl_poly_complex_workspace_free() to deallocate the memory.

Parameters

v	The complex_workspace

Definition at line 75 of file poly.hpp.

References ccgsl_pointer, and count.

◆ complex_workspace() [4/5]

gsl::poly::complex_workspace::complex_workspace ( complex_workspace const & v )

inline

The copy constructor.

This creates a new reference to the workspace.

Parameters

v	The complex_workspace to copy.

Definition at line 86 of file poly.hpp.

References ccgsl_pointer, and count.

◆ ~complex_workspace()

gsl::poly::complex_workspace::~complex_workspace ( )

inline

The destructor only deletes the pointers if count reaches zero.

Definition at line 105 of file poly.hpp.

References ccgsl_pointer, and count.

◆ complex_workspace() [5/5]

gsl::poly::complex_workspace::complex_workspace ( complex_workspace && v )

inline

Move constructor.

Parameters

v	The complex_workspace to move.

Definition at line 117 of file poly.hpp.

References count.

Member Function Documentation

◆ empty()

bool gsl::poly::complex_workspace::empty ( ) const

inline

Find if the complex_workspace is empty.

Returns: true if has size zero; otherwise false

Definition at line 194 of file poly.hpp.

References ccgsl_pointer.

◆ get()

gsl_poly_complex_workspace * gsl::poly::complex_workspace::get ( ) const

inline

Get the gsl_poly_complex_workspace.

Returns: the gsl_poly_complex_workspace

Definition at line 220 of file poly.hpp.

References ccgsl_pointer.

Referenced by gsl::poly::complex_solve().

◆ operator bool()

gsl::poly::complex_workspace::operator bool ( ) const

inlineexplicit

Allow conversion to bool.

Returns: true or false according as this contains a pointer to a gsl_poly_complex_workspace

Definition at line 240 of file poly.hpp.

References ccgsl_pointer.

◆ operator!=()

bool gsl::poly::complex_workspace::operator!= ( complex_workspace const & v ) const

inline

Two complex_workspace are different equal if their elements are not identical.

Parameters

v	The complex_workspace to be compared with `this`

Returns: false or true according as this and v have identical elements or not

Definition at line 147 of file poly.hpp.

References operator==().

◆ operator<()

bool gsl::poly::complex_workspace::operator< ( complex_workspace const & v ) const

inline

A container needs to define an ordering for sorting.

This uses standard lexicographical ordering and so is not useful, for eaxmple, for checking, that a complex_workspace is nonnegative.

Parameters

v	The complex_workspace to be compared with `this`

Returns: false or true according as this is less than v lexicographically

Definition at line 159 of file poly.hpp.

References ccgsl_pointer.

◆ operator<=()

bool gsl::poly::complex_workspace::operator<= ( complex_workspace const & v ) const

inline

A container needs to define an ordering for sorting.

This uses standard lexicographical ordering and so is not useful, for eaxmple, for checking, that a complex_workspace is nonnegative.

Parameters

v	The complex_workspace to be compared with `this`

Returns: false or true according as this is less than or equal to v lexicographically

Definition at line 179 of file poly.hpp.

References ccgsl_pointer.

◆ operator=() [1/2]

complex_workspace & gsl::poly::complex_workspace::operator= ( complex_workspace && v )

inline

Move operator.

Parameters

v	The complex_workspace to move.

Returns: A reference to this.

Definition at line 126 of file poly.hpp.

References complex_workspace().

◆ operator=() [2/2]

complex_workspace & gsl::poly::complex_workspace::operator= ( complex_workspace const & v )

inline

The assignment operator.

This copies elementwise.

Parameters

v	The complex_workspace to copy

Definition at line 93 of file poly.hpp.

References ccgsl_pointer, and count.

◆ operator==()

bool gsl::poly::complex_workspace::operator== ( complex_workspace const & v ) const

inline

Two complex_workspace are identically equal if their elements are identical.

Parameters

v	The complex_workspace to be compared with `this`

Returns: true or false according as this and v have identical elements or not

Definition at line 139 of file poly.hpp.

References ccgsl_pointer.

Referenced by operator!=().

◆ operator>()

bool gsl::poly::complex_workspace::operator> ( complex_workspace const & v ) const

inline

A container needs to define an ordering for sorting.

This uses standard lexicographical ordering and so is not useful, for eaxmple, for checking, that a complex_workspace is nonnegative.

Parameters

v	The complex_workspace to be compared with `this`

Returns: false or true according as this is greater than v lexicographically

Definition at line 169 of file poly.hpp.

References ccgsl_pointer.

◆ operator>=()

bool gsl::poly::complex_workspace::operator>= ( complex_workspace const & v ) const

inline

A container needs to define an ordering for sorting.

This uses standard lexicographical ordering and so is not useful, for eaxmple, for checking, that a complex_workspace is nonnegative.

Parameters

v	The complex_workspace to be compared with `this`

Returns: false or true according as this is no less than v lexicographically

Definition at line 189 of file poly.hpp.

References ccgsl_pointer.

◆ swap()

void gsl::poly::complex_workspace::swap ( complex_workspace & v )

inline

Swap two complex_workspace.

This works even if the complex_workspace have different sizes because it swaps pointers.

Parameters

Definition at line 201 of file poly.hpp.

References ccgsl_pointer, and count.

◆ unique()

bool gsl::poly::complex_workspace::unique ( ) const

inline

Find if this is the only object sharing the gsl_poly_complex_workspace.

Returns: true or falses according as this is the only gen_workspace object sharing the gsl_poly_complex_workspace

Definition at line 226 of file poly.hpp.

References count.

◆ use_count()

size_t gsl::poly::complex_workspace::use_count ( ) const

inline

Find how many gen_workspace objects share this pointer.

Returns: the number of gen_workspace objects that share this pointer
