Constructor Summary

Vec_array(double[] data)
Creates a new instance of Vec_array by copying the input array

Vec_array(int size)
Creates a new instance of Vec_array.

Vec_array(Vec_array v)
Copy-creates a new instance of Vec_array.

Vec_array(Vec v)
Copy-create a new instance of Vec_array.

Method Summary

double[]	asArray() get the data
Vec	copy() return a copy of this, or some version that the user can manipulate at will.
double	get(int i) the i-th element
void	set(double[] d) Copy the vector from an array
void	set(int i, double d) set the i-th element

Constructor Detail

Vec_array

public Vec_array(int size)

Creates a new instance of Vec_array.

Parameters:

size - the number of dimensions of this vector

Vec_array

public Vec_array(double[] data)

Creates a new instance of Vec_array by copying the input array

Parameters:

data - the array to copy

Vec_array

public Vec_array(Vec_array v)

Copy-creates a new instance of Vec_array.

Parameters:

v - the vector to copy

Vec_array

public Vec_array(Vec v)

Copy-create a new instance of Vec_array. Less efficient than Vec_array(Vec_array) since it uses the interface to get elements

Parameters:

v - the vector to copy

Method Detail

get

public double get(int i)

Description copied from interface: Vec

the i-th element

Specified by:

get in interface Vec

set

public void set(int i,
                double d)

Description copied from interface: Vec

set the i-th element

Specified by:

set in interface Vec

Parameters:

i - the element to set

d - the value to set it to

set

public void set(double[] d)

Description copied from interface: Vec

Copy the vector from an array

Specified by:

set in interface Vec

Parameters:

d - the array to copy from

set

public void set(Vec v)

Description copied from interface: Vec

Copy the vector from an array

Specified by:

set in interface Vec

Parameters:

v - the vector to copy from

size

public int size()

Description copied from interface: Vec

the size of the vector

Specified by:

size in interface Vec

copy

public Vec copy()

Description copied from interface: Vec

return a copy of this, or some version that the user can manipulate at will. If the implementation of this is immutable, can return the original, or the implementation can do some kind of copy-on-write.

Specified by:

copy in interface Vec

Returns:

a copy of the data

asArray

public double[] asArray()

Description copied from interface: Vec

get the data

Specified by:

asArray in interface Vec

Returns:

the data as a double[]

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
