Constructor Summary
Constructors Constructor Description RWVectord()
Default constructor.
The vector will be of dimension zero.RWVectord(long dim)
A configuration of vector of length dim.RWVectord(long cPtr, boolean cMemoryOwn)
RWVectord(long n, double value)
Creates a Vector of length n and initialize all values in Vector to value
RWVectord(long n, double[] values)
Creates a Vector of length n and initialized with values from values
The method reads n values from values and do not check whether reading out of bounds.

getCPtr
public static long getCPtr(RWVectord obj)
-
delete
public void delete()
-
zero
public static RWVectord zero(int n)
Returns Vector of length n initialized with 0's
-
size
public long size()
The dimension of the configuration vector.
-
empty
public boolean empty()
True if the configuration is of dimension zero.
-
e
public EigenVectorXd e()
Accessor for the internal Eigen vector state.
-
getSubPart
public RWVectord getSubPart(long start, long cnt)
Extracts a sub part (range) of this Vector.- Parameters:
start
- [in] Start indexcnt
- [in] the number of elements to include- Returns:
-
setSubPart
public void setSubPart(long index, RWVectord part)
Set a part of the vector.- Parameters:
index
- [in] first index.part
- [in] the subpart to set.
-
norm2
public double norm2()
Returns the Euclidean norm (2-norm) of the configuration- Returns:
- the norm
-
norm1
public double norm1()
Returns the Manhatten norm (1-norm) of the configuration- Returns:
- the norm
-
normInf
public double normInf()
Returns the infinte norm ( \inf -norm) of the configuration- Returns:
- the norm
-
divide
public RWVectord divide(double s)
Scalar division.
-
multiply
public RWVectord multiply(double s)
Scalar multiplication.
-
negate
public RWVectord negate()
Unary minus.
-
leessThan
public boolean leessThan(RWVectord q)
Compares whether this is less than q
The less operator is defined such that the first index is the most significant. That is
if (*this)[0] < q[0] then true is returned. If (*this)[0] > q[0] false is returned and
only if (*this)[0] == q[0] is the next index considered.
