Method Detail

size

int size()

Retrieve the size of the vector.

Returns:

int; the size of the vector

cardinality

int cardinality()

Count the number of cells that have a non-zero value (ignores tolerance).

Returns:

int; the number of cells having non-zero value

get

AbstractDoubleScalar<U,?> get(int index)
                       throws ValueException

Retrieve a value from the vector.

Parameters:

index - int; the index to retrieve the value at

Returns:

the value as a DoubleScalar

Throws:

ValueException - in case index is out of bounds

getSI

double getSI(int index)
      throws ValueException

Retrieve the value stored at a specified position in the standard SI unit.

Parameters:

index - int; index of the value to retrieve

Returns:

double; value at position index in the standard SI unit

Throws:

ValueException - when index out of range (index < 0 or index >= size())

getInUnit

double getInUnit(int index)
          throws ValueException

Retrieve the value stored at a specified position in the original unit.

Parameters:

index - int; index of the value to retrieve
