Functions
template<typename numtype >
std::string	gpu::show (const numtype *a, size_t rows, size_t cols, const std::string &name="")
	Show a 2D array as a string, base implementation.
template<typename numtype , size_t rows, size_t cols>
std::string	gpu::show (const std::array< numtype, rows *cols > &a, const std::string &name="")
	Overload of show() for std::array.
template<size_t rows, size_t cols>
std::string	gpu::show (const std::array< float, rows *cols > &a, const std::string &name="")
	Overload of show() for float std::array.
void	gpu::range (float *input, size_t N, float start=0.0, float step=1.0)
	Populate the array with a range of values. This is mostly for testing purposes.
template<size_t N>
void	gpu::range (std::array< float, N > &input, float start=0.0, float step=1.0)
	Overload of range() for std::array.
void	gpu::randint (float *a, size_t N, std::mt19937 &gen, int min=-1, int max=1)
	Populate the array with random integers.
template<typename numtype , size_t size>
void	gpu::randint (std::array< numtype, size > &a, std::mt19937 &gen, int min=-1, int max=1)
	Overload of randint() for std::array.
void	gpu::randn (float *a, size_t N, std::mt19937 &gen, float mean=0.0, float std=1.0)
	Populate the array with random floats, generated from a Gaussian distribution.
template<size_t size>
void	gpu::randn (std::array< float, size > &a, std::mt19937 &gen, float mean=0.0, float std=1.0)
	Overload of randn() for std::array.
void	gpu::eye (float *a, size_t N)
	Populate a square matrix with the identity matrix.
void	gpu::transpose (float *input, float *output, size_t M, size_t N)
	Transpose a matrix.
void	gpu::flip (float *a, size_t R, size_t C, bool horizontal=true)
	Flip a matrix horizontally or vertically.
bool	gpu::isclose (float *a, float *b, size_t n, float tol=1e-3)
	Determine if the values of two arrays are close to each other.
