Detailed Description

This class handles matrix_long_double objects as shared handles.

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

Note that matrix_long_double_views are implemented as matrix_long_double objects here.

Note that in C++11 it is possible to iterate over the rows of a matrix_long_double using

for( auto row : matrix_long_double ){ ... }

gsl::matrix_long_double

This class handles matrix_long_double objects as shared handles.

Definition: matrix_long_double.hpp:57

gsl::matrix_long_double::row

vector_long_double row(size_t const i)

C++ version of gsl_matrix_long_double_row().

Definition: matrix_long_double.hpp:775

Otherwise,

for( matrix_long_double::iterator i = matrix_long_double.begin(); i != matrix_long_double.end(); ++i ){
  vector_long_double row = *i;
  ...
}

will achieve the same effect. But if the element pointed to by i is used more than once, do not use

i-> ...

because each call of operator->() creates a new and different vector_long_double.

◆ wrap_gsl_matrix_long_double_without_ownership()

void gsl::matrix_long_double::wrap_gsl_matrix_long_double_without_ownership ( gsl_matrix_long_double * v )

inline

This function is intended mainly for internal use.

It allows this to point to a gsl_matrix_long_double without the possibility deleting it when this is no longer in scope. It is the responsibility of the programmer to delete v. The function is used internally for converting a function that takes a gsl::matrix_long_double* argument to one that takes a gsl_matrix_long_double* argument.

Parameters

v	The gsl_matrix_long_double
