 Constructor that initializes the length and possibly data. More...

 NumArray (const NumArray &array)
 Copy constructor.

 ~NumArray ()
 Default destructor.

NumArray< T > & operator= (const NumArray< T > &array)
 Copies the array object by constructing a new NumArray.

NumArray< T > & operator= (const T &array)
 Set all elements of the array to val.

void plus (const NumArray< T > &x, const NumArray< T > &y)
 Sets the array equal to the pair-wise value x + y.

void minus (const NumArray< T > &x, const NumArray< T > &y)
 Sets the array equal to the pair-wise value x - y.

void times (const NumArray< T > &x, const NumArray< T > &y)
 Sets the array equal to the pair-wise value x * y.

void divide (const NumArray< T > &x, const NumArray< T > &y)
 Sets the array equal to the pair-wise value x / y.

void plus (const NumArray< T > &x, const T &z)
 Sets the array equal to the value x[i] + z.

void minus (const NumArray< T > &x, const T &z)
 Sets the array equal to the value x[i] - z.

void times (const NumArray< T > &x, const T &z)
 Sets the array equal to the value x[i] * z.

void divide (const NumArray< T > &x, const T &z)
 Sets the array equal to the value x[i] / z.

NumArray< T > operator- ()
 Changes the sign of elements in the array.

NumArray< T > & operator+= (const NumArray< T > &x)
 Adds the values of x elementwise to the current array.

NumArray< T > & operator-= (const NumArray< T > &x)
 Subtracts the values of x elementw to the current array.ise.

NumArray< T > & operator *= (const NumArray< T > &x)
 Multiplies the values of x elementwise to the current array.

NumArray< T > & operator/= (const NumArray< T > &x)
 Divides the values of x elementwise to the current array.

NumArray< T > & operator+= (const T &z)

Detailed Description

template<class T>
class NumArray< T >

An array data type for numerical data.

NumArray extends the definition of SimpleArray to include numerical vector operations.

Constructor & Destructor Documentation

template<class T>
NumArray< T >::NumArray (  const size_type    len,
T *    d = ((T*)0),
const EnumDataOwned    o = DataNotOwned
)  [inline, explicit]
 

Constructor that initializes the length and possibly data.

The len parameter specifies the length of the array. If the d parameter is null, then the array is initialized to have a zero value. Otherwise, this array is assumed to have length len. The initialization of the array then depends upon the value of the o parameter. If o is DataNotOwned (the default), then the data is copied from d. Otherwise, the internal point is set to d and the internal ownership flag is set to o.
