Detailed Description

This class handles vector_float objects as shared handles.

It models a random access container so that STL functions work with vector_float.

Note that vector_float_views are implemented as vector_float objects here.

If you want to use a std::vector<float> or similar object as if it were a gsl::vector_float object, use the constructor that takes a stride argument. But use it with caution. Changing the size of the original object does not change the size of the gsl::vector_float object; so it may be safer to create gsl::vector_float objects in this way as needed.

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

Parameters

v	The vector_float

◆ vector_float() [4/10]

gsl::vector_float::vector_float ( std::initializer_list< float > initializer_list )

Parameters

initializer_list The initializer_list.

◆ vector_float() [5/10]

Parameters

v	The vector_float to copy.

Definition at line 132 of file vector_float.hpp.

References count.

◆ vector_float() [6/10]

gsl::vector_float::vector_float ( vector_float & v )

Parameters

v	The vector_float to copy.

◆ vector_float() [7/10]

template<typename V >

gsl::vector_float::vector_float	(	V &	v,
		size_t const	stride = `1`
	)

inline

Construct from an object that implements data() and size().

This is primarily intended to allow you to construct from a std::vector<float> or std::array<float,size_t> object. But it could be used to construct a subvector. This constructor shares the data with the original object. But the price of efficiency is safety. If you change the size of v the size of the gsl::vector_float does not change. Stride is normally set to 1 and allows us to define a constructor. But it can be set to another value to indicate, for example, that you only wish every second element to be included in this.

Parameters

v	The object that you want this to share data with.
stride	The stride.
