# range(4rheolef)

index range for a subset of a vector (rheolef-7.2)

## NAME

range - index range for a subset of a vector (rheolef-7.2)

## DESCRIPTION

This class represents a range of index for addressing a subset of the **vec(4)** container.

## EXAMPLE

```
    vec<double> x (100, 3.14);
    vec<double> y = x(range(0,50));
    dout << y << endl;
```

## IMPLEMENTATION

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

```
struct range {
  using size_type = size_t;
  range (size_type start=0, size_type stop=0);
  size_type start() const;
  size_type size() const;
  static range all();
```

```
};
```
