Member Function Documentation

template<class T>

void Vector< T >::assign	(	Int	newn,
		const T &	c
	)		[inline]

Resize and assign a constant value.

Definition at line 141 of file matrix.h.

    {
        if( newn != nn ) {
            if( v != NULL ) {
                delete[] v;

template<class T>

Vector<T>& Vector< T >::operator=

(

const Vector< T > &

rhs

)

[inline]

Assigns an existing vector.

Postcondition: normal assignment via copying has been performed; if vector and rhs were different sizes, vector has been resized to match the size of rhs.
