vec

distributed vector

# Description

This vector class supports both the sequential and the distributed memory model. In addition, standard linear algebra is supported.

# Example

        vec<double> x (100, 3.14);
        vec<double> y (100, 6.28);
        vec<double> z = 2.5*x + y;
        dout << x << endl;

# Implementation

This documentation has been generated from file linalg/lib/vec.h

The vec class is a template class with both the floating type and the memory model as parameters. The implementation bases on the disarray container.

template <class T, class M = rheo_default_memory_model>
class vec : public disarray<T, M> {
public:
// typedef:
typedef disarray<T, M> base;
typedef T value_type;
typedef typename base::size_type size_type;
typedef std::ptrdiff_t difference_type;
typedef range range_type;
typedef typename base::reference reference;
typedef typename base::const_reference const_reference;
typedef typename base::iterator iterator;
typedef typename base::const_iterator const_iterator;
typedef typename float_traits <value_type>::type float_type;

vec (const vec<T,M>&);
