Class Vector<R extends Num>

java.lang.Object
edu.wpi.first.math.Matrix<R,​N1>
edu.wpi.first.math.Vector<R>
Type Parameters:
R - The number of rows in this matrix.

public class Vector<R extends Num>
extends Matrix<R,​N1>
A shape-safe wrapper over Efficient Java Matrix Library (EJML) matrices.

This class is intended to be used alongside the state space library.

  • Constructor Details

    • Vector

      public Vector​(Nat<R> rows)
      Constructs an empty zero vector of the given dimensions.
      Parameters:
      rows - The number of rows of the vector.
    • Vector

      public Vector​(org.ejml.simple.SimpleMatrix storage)
      Constructs a new Vector with the given storage. Caller should make sure that the provided generic bounds match the shape of the provided Vector.

      NOTE:It is not recommended to use this constructor unless the SimpleMatrix API is absolutely necessary due to the desired function not being accessible through the Vector wrapper.

      Parameters:
      storage - The SimpleMatrix to back this vector.
    • Vector

      public Vector​(Matrix<R,​N1> other)
      Constructs a new vector with the storage of the supplied matrix.
      Parameters:
      other - The Vector to copy the storage of.

    • times

      public Vector<R> times​(double value)
      Description copied from class: Matrix
      Multiplies all the elements of this matrix by the given scalar.
      Overrides:
      times in class Matrix<R extends Num,​N1>
      Parameters:
      value - The scalar value to multiply by.
      Returns:
      A new matrix with all the elements multiplied by the given value.
    • div

      public Vector<R> div​(int value)
      Description copied from class: Matrix
      Divides all elements of this matrix by the given value.
      Overrides:
      div in class Matrix<R extends Num,​N1>
      Parameters:
      value - The value to divide by.
      Returns:
      The resultant matrix.
    • div

      public Vector<R> div​(double value)
      Description copied from class: Matrix
      Divides all elements of this matrix by the given value.
      Overrides:
      div in class Matrix<R extends Num,​N1>
      Parameters:
      value - The value to divide by.
      Returns:
      The resultant matrix.
